How can I use Perl for Floating Point Arithmetic in a manner like a calculator does.

For Example:

#!/usr/bin/perl

$number = 0.5299 - 0.5300;

print $number;

...

Prints: -9.9999999999989e-05

I want: -0.0001

Any help is appreciated!!!

Thanks,
Dan

Thank You...

"printf "%.4f",-9.9999999999989e-05"
I read something to that effect, but I didn't think it as the problem...

Again thank you!
