Math::BigInt::CalcEmu - Emulate low-level math with BigInt code
SYNOPSIS
use Math::BigInt::CalcEmu;
DESCRIPTION
Contains routines that emulate low-level math functions in BigInt, e.g. optional routines the low-level math package does not provide on
its own.
Will be loaded on demand and called automatically by BigInt.
Stuff here is really low-priority to optimize, since it is far better to implement the operation in the low-level math libary directly,
possible even using a call to the native lib.
METHODS
__emu_bxor
__emu_band
__emu_bior

Math::BigInt::FastCalc(3pm) Perl Programmers Reference Guide Math::BigInt::FastCalc(3pm)NAME
Math::BigInt::FastCalc - Math::BigInt::Calc with some XS for more speed
SYNOPSIS
Provides support for big integer calculations. Not intended to be used by other modules. Other modules which sport the same functions can
also be used to support Math::BigInt, like Math::BigInt::GMP or Math::BigInt::Pari.
DESCRIPTION
In order to allow for multiple big integer libraries, Math::BigInt was rewritten to use library modules for core math routines. Any module
which follows the same API as this can be used instead by using the following:
use Math::BigInt lib => 'libname';
'libname' is either the long name ('Math::BigInt::Pari'), or only the short version like 'Pari'. To use this library:
use Math::BigInt lib => 'FastCalc';
Note that from Math::BigInt v1.76 onwards, FastCalc will be loaded automatically, if possible.
STORAGE
FastCalc works exactly like Calc, in stores the numbers in decimal form, chopped into parts.
METHODS
The following functions are now implemented in FastCalc.xs:
_is_odd _is_even _is_one _is_zero
_is_two _is_ten
_zero _one _two _ten
_acmp _len
_inc _dec
__strip_zeros _copy

I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.
