BIN


Returns a binary (base 2) string representation of an integer

Syntax:
declare function Bin ( byval number as ubyte, byval digits as long ) as string
declare function Bin ( byval number as ushort, byval digits as long ) as string
declare function Bin ( byval number as ulong, byval digits as long ) as string
declare function Bin ( byval number as ulongint, byval digits as long ) as string
declare function Bin ( byval number as const any ptr, byval digits as long ) as string

Usage:
result = Bin[$]( number [, digits ] )

Parameters:
number
A number or expression evaluating to a number. A floating-point number will be converted to a longint.
digits
Desired number of digits in the returned string.

Return Value:
A string containing the unsigned binary representation of number.

Description:
Returns a string representing the unsigned binary value of the integer number. Binary digits range from 0 to 1.

If you specify digits > 0, the result string will be exactly that length. It will be truncated or padded with zeros on the left, if necessary.

The length of the string will not go longer than the maximum number of digits required for the type of number (32 for a long, 64 for a Longint).

If you want to do the opposite, i.e. convert an binary string back into a number, the easiest way to do it is to prepend the string with "&B", and convert it to an integer type, using a function like Cint, similarly to a normal numeric string. E.g. Cint("&B101")

Examples:
Print Bin(54321)
Print Bin(54321, 5)
Print Bin(54321, 20)
will produce the output:

1101010000110001
10001
00001101010000110001
