bcmod()

The docs (see below) for bcmod() are rather skimpy. Does anyone have a clue as to how it works. Basically I want to do this (below code). PS: I am new to PHP but not to programming in general. Tom $i = 1; while (something true){

    $modulus = the_modulus_of($i / 4); // does php do % instead of /?
    if($modulus == 0){
         do_this_this_time();
    }

$i++; } *bcmod* (PHP 3, PHP 4 ) bcmod -- Get modulus of an arbitrary precision number Description string bcmod ( string left_operand, string modulus) Get the modulus of the left_operand using modulus.
