Math weirdness with doubles...

Ok... It's Friday and maybe my brain is dead, but I'm having a weird problem with some basic math. Here's a little snippet of the code I'm working with: --------------------------- echo "<p>Current:$currentAmount:".gettype($currentAmount)." - Paid:$paidAmount:".gettype($paidAmount)."</p>"; $currentAmount = $currentAmount-$paidAmount; echo "<p>Final Current: $currentAmount"; ----------------- Straightforward... Yeah? Here's a sample of the output: Current:97.6:double - Paid:97.6:double Final Current: 1.42108547152E-014 Now if both $currentAmount and $paidAmount are doubles, subtracting them should yield a zero, shouldn't it? -- jon ------------------- jon roig web developer email: jon@trafficdesigns.com phone: 888.230.7557 --- Outgoing mail is certified Virus Free.
