Methods summary
`public string`	# `longToBinary( integer $long )` Given a long integer, returns the number converted to a binary string. This function accepts long integer values of arbitrary magnitude and uses the local large-number math library when available. Given a long integer, returns the number converted to a binary string. This function accepts long integer values of arbitrary magnitude and uses the local large-number math library when available. Parameters `$long` The long number (can be a normal PHP integer or a number created by one of the available long number libraries) Returns string $binary The binary version of $long
`public integer`	# `binaryToLong( string $str )` Given a binary string, returns the binary string converted to a long number. Given a binary string, returns the binary string converted to a long number. Parameters `$str` $binary The binary version of a long number, probably as a result of calling longToBinary Returns integer $long The long number equivalent of the binary string $str
`public`	# `base64ToLong( $str )`
`public`	# `longToBase64( $str )`
`public integer`	# `rand( integer $stop, integer $stop,…, integer $step,… )` Returns a random number in the specified range. This function accepts $start, $stop, and $step values of arbitrary magnitude and will utilize the local large-number math library when available. Returns a random number in the specified range. This function accepts $start, $stop, and $step values of arbitrary magnitude and will utilize the local large-number math library when available. Parameters `$stop` $start The start of the range, or the minimum random number to return `$stop`,… The end of the range, or the maximum random number to return `$step`,… The step size, such that $result - ($step * N) = $start for some N Returns integer $result The resulting randomly-generated number
