Re: bcmath, standart ?

You might want to consider using a fallback method: If the bcmath module is loaded use bcmod() otherwise check if the fmod() function is defined (added to php4/ext/math.c back in February IIRC) and use that one, or if that functions is not defined fall back to a simple implementation like: function modf($a, $b) { $r = $a / $b; $i = intval($r); return ($r - $i) * $b; } (from some old code for numPHP I got lying around) As far as GMP, for what I see in the PHP source only the integer functions have been wrapped, not the floating point ones. --- Pierre-Alain Joye <paj@pearfr.org> wrote: > Hello, > > > Currently need the modulo operator, the problem is % is limited to int in php > (direct uses of the c operator after conversion to long), and is not enough > for my needs (IBAN, BAN,... for Validate). > > Should I consider the bcmath ( or gmp) as a widely used module ?
