Can anyone comment how they handle floating point precision situations

Here is a basic toy program:
#!/usr/bin/perl
use strict;
my $total = 0;
my $a = 21835.30;
my $b = -21715.90;
my $c = 9652.20;
my $d = -9771.60;
print ("total = $total\n");
$total += $a;

Say if (not) instead. The looser binding makes it easier to use and
the fact that it is three letters long (rather than one skinny
