Allows you to use arbitrarily big rationals. Math::BigRat is shipped with the Perl 5.8 source kit.
For example:
#!/usr/local/bin/perl -w
use Math::BigRat;
my $rat = Math::BigRat->new('2/7');
print $rat->bstr(), "\n";Math::BigRat implements the following methods.
| new |
new(value)
Creates a new Math::BigRat object. You can use all types of input for new(): '3/5', '2/33', '6/9', etc.
| denominator |
denominator()
Returns a copy of the denominator as a positive BigInt:
my $rat = Math::BigRat->new('2/7')
print $rat->denominator(), "\n"; # Prints 7| numerator |
numerator()
Returns a copy of the numerator as a signed BigInt:
my $rat = Math::BigRat->new('2/7');
print $rat->numerator(), "\n"; # Prints 2| parts |
parts()
Returns a list consisting of a signed numerator and unsigned denominator. Both are BigInts.
my($n, $d) = $rat->parts(); ### Ewwww, rat parts! print "numerator: $n\n"; print "denominator: $d\n";
