Math-BigNum

Transparent interface to Math::GMPq, Math::GMPz and Math::MPFR.

DESCRIPTION

Math::BigNum provides a correct, intuitive and transparent interface to the GMP and MPFR numerical libraries.

SYNOPSIS

  1. use 5.014;
  2. use Math::BigNum qw(:constant);
  4. # Big numbers
  5. say ((100->fac + 1) / 2);
  6.   # => 466631077219720763408496194281333502453579841321908107 \
  7.   #    342964819476087999966149578044707319880782591431268489 \
  8.   #    60413611879125592605458432000000000000000000000000.5
  10. # Small numbers
  11. say sqrt(1 / 100->fac);     # => 1.035137811175626471320494591657[...]e-79
  13. # Rational numbers
  14. my $x = 2/3;
  15. say $x*3;                   # => 2
  16. say 2/$x;                   # => 3
  17. say $x->as_frac;            # => "2/3"
  19. # Floating-point numbers
  20. say "equal" if (1.1 + 2.2 == 3.3);     # => "equal"
