Math::MPFR Description

Perl interface to the MPFR (floating point) library Math::MPFR is a bigfloat module utilising the MPFR library. Basically this module simply wraps the 'mpfr' floating point functions provided by that library.SYNOPSIS use Math::MPFR qw(:mpfr); # '@' can be used to separate mantissa from exponent. For bases # that are new($str); # Create another Math::MPFR object with precision # of 100 bits and an initial value of NaN. my $bn2 = Rmpfr_init2(100); # Assign the value -2314.451 to $bn1. Rmpfr_set_d($bn2, -2314.451, GMP_RNDN); # Create another Math::MPFR object that holds # an initial value of NaN and has the default precision. my $bn3 = Rmpfr_init(); # Or using instead the new() constructor: # my $bn3 = Math::MPFR->new(); # Perform some operations ... see 'FUNCTIONS' below. # see 'OPERATOR OVERLOADING' below for docs re # operator overloading . . # print out the value held by $bn1 (in octal): print Rmpfr_get_str($bn1, 8, 0, $rnd), " "; # print out the value held by $bn1 (in decimal): print Rmpfr_get_str($bn1, 10, 0, $rnd), " "; # or just make use of overloading : print $bn1, " "; # is base 10, and uses 'e' rather than '@'. # print out the value held by $bn1 (in base 16) using the # 'TRmpfr_out_str' function. (No newline is printed - unless # it's supplied as the optional fifth arg. See the # 'TRmpfr_out_str' documentation below.) TRmpfr_out_str(*stdout, 16, 0, $bn1, $rnd); Requirements: · Perl · MPFR and GMP C libraries
