NAME

Math::ModInt::Perl - modular integer arithmetic, powered by native Perl

VERSION

This documentation refers to version 0.012 of Math::ModInt::Perl.

SYNOPSIS

  use Math::ModInt::Perl;

  $a = Math::ModInt::Perl->new(3, 7);             # 3 [mod 7]
  $b = $a->new(4);                                # 4 [mod 7]
  $c = $a + $b;                                   # 0 [mod 7]
  $d = $a**2 - $b/$a;                             # 3 [mod 7]

  $m = $b->modulus;                               # 7
  $r = $b->residue;                               # 4
  $r = $b->signed_residue;                        # -3
  $t = "$b";                                      # 'mod(4, 7)'

  $bool = $c == $d;                               # false

  $a->optimize_time;                  # aim for less cpu cycles
  $a->optimize_space;                 # aim for less memory space
  $a->optimize_default;               # reset optimization choice

DESCRIPTION

Math::ModInt::Perl is a generic implementation of Math::ModInt for small moduli, using native Perl integer arithmetic. Like all Math::ModInt implementations, it is loaded behind the scenes when there is demand for it, without applications needing to worry about it.

This implementation is capable of different optimization strategies per modulus. See optimize_time, optimize_space, optimize_default in Math::ModInt.
