Sorry, if breaking any forum rules.
<?php
$amount=19.90;
$mul=0.10;
$ztmpamt=$amount*100;
$zbidmul=$mul*100;
echo "amount:".$ztmpamt." mul:".$zbidmul;
echo "<br>";
$zcheckmultiple= $ztmpamt % $zbidmul;
echo "Why this is not zero:".$zcheckmultiple;
echo "<br>";
echo "amt:".$ztmpamt.":mul:".$zbidmul;
echo "<br>";
$result= 1990 % 10;
echo "This is zero:".$result;
echo "<br>";
