Sumário: (alpha) perl interface to C's _Decimal64 operations.
Descrição:
Note that this module is alpha software. It seems to work ok
for me on MS Windows (compiling with gcc-4.6.3, gcc-4.7.0)
but, at time of release, is untested elsewhere.
Math::Decimal64 supports up to 16 decimal digits of significand
(mantissa) and an exponent range of -383 to +384.
The smallest expressable value is -9.999999999999999e384 (which
is also equivalent to -9999999999999999e369).
The largest expressable value is 9.999999999999999e384 (which
also equivalent to 9999999999999999e369).
The closest we can get to zero is (plus or minus) 1e-384
(which is also equivalent to 1000000000000000e-399).
This module allows decimal floating point arithmetic via
operator overloading - see "OVERLOADING".
In the documentation that follows, "$mantissa" is a perl scalar
holding a string of up to 16 decimal digits:
$mantissa = '1234';
$mantissa = '1234567890123456';
For many values, it normally shouldn't matter if $mantissa is
assigned as a number:
$mantissa = 1234; # should work ok.
But on some perls there are values that *need* to be assigned
as a string. For example, on perls where nvtype is an 8 byte
'double':
$mantissa = '-9307199254740993'; # works fine
$mantissa = -9307199254740993; # will assign wrong value
So ... where you see "$mantissa" in the following docs, think
*string* of up to 16 decimal digits".
