use Math::NV qw(:all);
my $nv = nv('1e-298'); # ie the number 10 ** -298
my($nv, $iv) = nv('1e-298');
The above snippet will assign a correct value for 1e-298 to $nv.
Doing simply "$nv = 1e-298;" may *not* do that. (The test suite
specifically checks and reports whether 1e-298 can correctly be
assigned directly to a perl scalar. It also checks some other
values).
$iv is set to the number of characters in the input string that
were unparsed.
The nv() function assigns the value at the C (XS) level using
either the C function strtod() or strtold() - whichever is
appropriate for your perl's configuration.
Obviously, we are therefore relying upon absence of bugs in the
way your compiler/libc assigns strings to floats. (Hopefully, if
such bugs are present, this will become evident in the form of
failures in the module's test suite.)
NOTE:
For an NV $nv, it's not guaranteed that nv($nv) and nv("$nv")
will be equivalent. For example, on many of my 64-bit MS Win
builds of perl, a print() of nv('1e-298') will output 1e-298,
whereas a print() of nv(1e-298) outputs 9.99999999999999e-299.
