%description
All operators (including basic math operations) are overloaded if you
declare your big integers as

$i = new Math::BigInt '123_456_789_123_456_789';

Operations with overloaded operators preserve the arguments which is
exactly what you expect.

* Input

Input values to these routines may be any string, that looks like a
  number and results in an integer, including hexadecimal and binary
  numbers.

Scalars holding numbers may also be passed, but note that non-integer
  numbers may already have lost precision due to the conversion to float.
  Quote your input if you want BigInt to see all the digits:

$x = Math::BigInt->new(12345678890123456789);	# bad
  	$x = Math::BigInt->new('12345678901234567890');	# good

You can include one underscore between any two digits.

This means integer values like 1.01E2 or even 1000E-2 are also accepted.
  Non-integer values result in NaN.

Hexadecimal (prefixed with "0x") and binary numbers (prefixed with "0b")
  are accepted, too. Please note that octal numbers are not recognized by
  new(), so the following will print "123":

perl -MMath::BigInt -le 'print Math::BigInt->new("0123")'

To convert an octal number, use from_oct();

perl -MMath::BigInt -le 'print Math::BigInt->from_oct("0123")'

Currently, Math::BigInt::new() defaults to 0, while Math::BigInt::new('')
  results in 'NaN'. This might change in the future, so use always the
  following explicit forms to get a zero or NaN:

$zero = Math::BigInt->bzero();
  	$nan = Math::BigInt->bnan();

'bnorm()' on a BigInt object is now effectively a no-op, since the
  numbers are always stored in normalized form. If passed a string, creates
  a BigInt object from the input.

* Output

Output values are BigInt objects (normalized), except for the methods
  which return a string (see the SYNOPSIS manpage).

Some routines ('is_odd()', 'is_even()', 'is_zero()', 'is_one()',
  'is_nan()', etc.) return true or false, while others ('bcmp()',
  'bacmp()') return either undef (if NaN is involved), <0, 0 or >0 and are
  suited for sort.
