BitchX scripting function $isnumber()

isnumber
Function
$isnumber()
Usage
$isnumber(number base)
Returns
returns the empty value if nothing is passed to it; returns 0 if the value passed is not a number; returns 1 if the value passed is a number.
The "base" number is optional and should be prefixed by the character 'b'. ala, $isnumber(0x0F b16) for hexadecimal. The special base zero (b0) means to 'auto-detect'. Base must be between 0 and 36, inclusive. If not, it defaults to 0.
