rational support for Perl. For example, if you want to add the
fractions 1/2 + 3/8, you can use bigrat to calculate the result and
display it in fractional form: 7/8. Or in Perl terms:
my $frac1 = 1/2;
my $frac2 = 3/8;
print $frac1 + $frac2, "\n"; # Prints 7/8
As of Perl 5.8, bigrat is shipped with the Perl source kit.
