Now when you take the base 10 number 26.33333.... and try to convert it to base 3 you end up with 222.022222....
Now if you try the same number with just 1 decimal place 26.3 you end up with a different number.
The number of decimal places displayed is set from the calculator options screen. Among calculators that actually convert from one base to another, very few work with decimals places. InfoFind correctly calculates the results for you, but keep in mind that some fractional numbers do not fully translate to fractional numbers in another base.
Operator  Description 

\  Integer Division: Divides two numbers and returns an integer result (Number without the decimal portion). In division 10/3 = 3.333 but with integer division 10\3 = 3. 
Mod  Remainder: Divides two numbers and returns only the remainder. 10 Mod 3 = 1 
And  Performs a logical conjunction on two expressions. If, and only if, both expressions evaluate to True, result is True. If either expression evaluates to False, result is False. Examples: True And True = True, True And False = False 
Or  Performs a logical disjunction on two expressions. If either or both expressions evaluate to True, result is True. Examples: True Or True = True, True Or False = True, False Or False = False 
Xor  Performs a logical exclusion on two expressions. If one, and only one, of the expressions evaluates to True, result is True. Examples: True Xor True = False, True Xor False = True, False Xor False = False 
Eqv  Performs a logical equivalence on two expressions. Examples: True Eqv True = True, True Eqv False = False, False Eqv False = True 
Imp  Performs a logical implication on two expressions. Examples: True Imp False = False, False Imp True = True 
Not  Used to perform logical negation on an expression. Examples: Not True = False, Not False = True 
Function  Description 

Sqr(Number)  Returns the square root of a number. A factor of a number that when squared returns the number. Example: 3 = Sqr(9) because 3^2 = 9 
Atn(Number)  Returns the arctangent of a number. The Atn function takes the ratio of two sides of a right triangle (number) and returns the corresponding angle in radians. The ratio is the length of the side opposite the angle divided by the length of the side adjacent to the angle. The range of the result is pi /2 to pi/2 radians. 
Cos(Number)  Returns the cosine of an angle. The Cos function takes an angle and returns the ratio of two sides of a right triangle. The ratio is the length of the side adjacent to the angle divided by the length of the hypotenuse. The result lies in the range 1 to 1. 
Sin(Number)  Returns the sine of an angle. The Sin function takes an angle and returns the ratio of two sides of a right triangle. The ratio is the length of the side opposite the angle divided by the length of the hypotenuse. The result lies in the range 1 to 1. 
Tan(Number)  Returns the tangent of an angle. Tan takes an angle and returns the ratio of two sides of a right triangle. The ratio is the length of the side opposite the angle divided by the length of the side adjacent to the angle. 
Exp(Number)  Returns e (the base of natural logarithms) raised to a power. If the value of number exceeds 709.782712893, an error occurs. The constant e is approximately 2.718282. 
Log(Number)  Returns the natural logarithm of a number. The natural logarithm is the logarithm to the base e. The constant e is approximately 2.718282. 
Rnd()  Returns a random number. The Rnd function returns a value less than 1 but greater than or equal to 0. To return a random number in a specified range use the following formula: Int((High  Low + 1) * Rnd() + Low) 
Abs(Number)  Returns the absolute value of a number. Examples: Abs(10) = 10, Abs(10) = 10 
Round(Number, DecimalPlaces)  Returns a number rounded to a specified number of decimal places. 
Fix(Number)  Returns the integer portion of a number. The difference between Int and Fix is that if number is negative, Int returns the first negative integer less than or equal to number, whereas Fix returns the first negative integer greater than or equal to number. For example, Int converts 8.4 to 9, and Fix converts 8.4 to 8. 
Int(Number) 
Trigonometry is a topic of mathematics that defines the dimensions of triangles and angles. There are two types of trigonometry  plane trigonometry, which calculates triangles on a flat surface, and spherical trigonometry, which calculates triangles that are sections on the surface of a sphere. 
The common trigonometry functions used in InfoFind (Atn, Cos, Sin, and Tan) work in Radians rather then Degrees. To convert degrees to radians, multiply degrees by pi /180. To convert radians to degrees, multiply radians by 180/pi. The functions below can be copied to the function editor and used for this purpose. 
'Convert from degrees to radians. Function DegreesToRadians(Degrees) DegreesToRadians = Degrees * 3.14159265358979 / 180 End Function 'Convert from radians to degrees. Function RadiansToDegrees(Radians) RadiansToDegrees = Radians * 180 / 3.14159265358979 End Function 
The following picture shows the common Trigonometry functions and how they are calculated. Arctangent (Atn) is the inverse function of Tangent. Examples: Atn(Tan(X)) = X and Tan(Atn(X)) = X 

Function  Description 

Date  Returns the current date according to the setting of your computer's system date and time. 
Time  Returns the current time according to the setting of your computer's system date and time. 
Now  Returns the current date and time according to the setting of your computer's system date and time. 
DateAdd(Interval, Number, Date)  Returns a date to which a specified time interval has been added. Interval can be of the following values: ("yyyy" = Year, "q" = Quarter, "m" = Month, "y" = Day of year, "d" = Day, "w" = Weekday, "ww" = Week of year, "h" = Hour, "n" = Minute, "s" = Second) Example: 1/31/2011 = DateAdd("m", 1, #12/31/10#) 
DateDiff(Interval, Date1, Date2)  Returns the number of intervals between two dates. You can use the DateDiff function to determine how many specified time intervals exist between two dates. For example, you might use DateDiff to calculate the number of days between two dates, or the number of weeks between today and the end of the year. Interval are specified with the same values as the DateAdd function listed above. Exaple: 31 = DateDiff("d", #12/31/10#, #1/31/11#) 
DatePart(Interval, Date)  Returns the specified part of a given date. Interval are specified with the same values as the DateAdd Function listed above. Example: 4 = DatePart("q", #12/31/11#) 
Easter  

In Christianity Easter is an annual festival that Christians celebrate the Resurrection of Jesus Christ. Many publications list Easter as the first Sunday after the first Full Moon following the vernal equinox. That definition is actually incorrect and the following rules are how Easter is determined. The date of Easter occurs on the first Sunday following the Paschal Full Moon for the year. The Paschal Full Moon is the first Ecclesiastical Full Moon date after March 20. Ecclesiastical means related to the Church and Ecclesiastical Full Moons are approximated astronomical full moon dates, not actual astronomical full moon dates. There are several different dates for Easter. Two methods are in use today with Western Churches celebrating Easter on one date calculated using the Gregorian calendar and Eastern Orthodox Churches celebrating it on another date calculated using the Julian calendar.  
Julian calendar: The Julian calendar was a solar calendar introduced by the Roman Emperor Julius Caesar in 46 B.C. to replace the Roman calendar. The Roman calendar was a lunisolar calendar but it was maintained by corrupt politicians who would add or remove days from the calendar as they wanted so it became inaccurate for farming and for festivals. In the Julian calendar a common year is defined to comprise 365 days, and every forth year is a leap year comprising 366 days. The Julian calendar was superseded by the Gregorian calendar.  
Gregorian calendar: The Gregorian calendar was introduced by Pope Gregory XIII in 1582 to replace the Julian calendar; and the Gregorian calendar is the calendar now used as the civil calendar in most countries. The Gregorian calendar differs only slightly from the Julian calendar and was introduced because over time differences had accumulated compared to the actual solar time period so Easter was occurring before the Vernal Equinox. Like the Julian calendar in the Gregorian calendar a common year is defined to comprise 365 days, and leap years comprising of 366 days; but in the Gregorian calendar every year that is exactly divisible by four is a leap year, except for centurial years, which must be divisible by 400 to be leap years. Thus, 2000 is a leap year, but 1900 and 2100 are not leap years. 
Function  Description 

Easter(Year)  Returns the date of Easter for Western Churches for any year from 1583 to 4099. 
EasterOrthodox(Year)  Returns the date of Easter for Eastern Orthodox Churches for any year from 1583 to 4099. 
EasterJulian(Year)  Returns the date of Easter for the Julian calendar for any year from 326 AD. This method is no longer used today. 
Function  Description 

HTMLColor(RGB(Number, Number, Number))  The function HTMLColor() takes a Standard Red, Green, and Blue Color Number between 0 and 255 and prints out the HTML Hexadecimal Equivalent that is used for specifying colors on web pages. For example: #0054E3 = HTMLColor(RGB(0, 84, 227)) 
BlendColor(Color, Color)  The function BlendColor() is a function that combines two colors and returns a new Color in HTML Hexadecimal Format. BlendColor is actually used internally by InfoFind to determine how to draw controls of the same color but a different shade. Parameters for BlendColor can be specified in either HTML Color or in Red, Green, Blue Color Format. For example: #7FA9F1 = BlendColor(RGB(0, 84, 227), #FFFFFF)
