Re: shocking imprecision

[rgiskard]

xrmb sprintf is the way to go, but if you're feeling lazy; just add "use bigrat;" (aka. big rational, cpan: bigrat) to the top of your proggie. It is not optimal (neither is bignum), but it does increases precision.

Example: imprecise.pl

use bigrat;

print int(4.39 * 100) . "\n";

my $a = 4.39, $b = 100;
print int ($a*$b) ."\n";

my $ans = $a*$b;
print $a*$b ."\n";
print int ( $ans ) ."\n";

Output:

perl imprecise.pl
439
439
439
