Math::ModInt::BigInt - modular integer arithmetic, powered by Math::BigInt
This documentation refers to version 0.001 of Math::ModInt::BigInt.
use Math::ModInt qw(mod); $a = Math::ModInt->new(3, 76543); # 3 [mod 76543] $a = mod(3, 76543); # 3 [mod 76543] $b = $a->new(4); # 4 [mod 76543] $c = $a + $b; # 7 [mod 76543] $d = $a**2 - $b/$a; # 25522 [mod 76543] print $a->residue, " [mod ", $b->modulus, "]"; # prints 3 [mod 76543] print "$a"; # prints mod(3, 76543) $bool = $c == $d; # false
Math::ModInt::BigInt is a generic implementation of Math::ModInt for arbitrarily large moduli. Like all Math::ModInt implementations, it is loaded behind the scenes when there is demand for it, without applications needing to worry about it.
Note, however, that values returned by residue or modulus may be Math::BigInt objects rather than plain Perl numbers when this implementation has actually been involved.
