Math::MPFR 2.03

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