THE MPIR LIBRARY
|
||||
|
||||
|
||||
MPIR is a library for arbitrary precision arithmetic, operating on signed
|
||||
integers, rational numbers, and floating point numbers. It has a rich set of
|
||||
functions, and the functions have a regular interface.
|
||||
|
||||
MPIR is designed to be as fast as possible, both for small operands and huge
|
||||
operands. The speed is achieved by using fullwords as the basic arithmetic
|
||||
type, by using fast algorithms, with carefully optimized assembly code for the
|
||||
most common inner loops for lots of CPUs, and by a general emphasis on speed
|
||||
(instead of simplicity or elegance).
|
||||
|
||||
MPIR is believed to be faster than any other similar library. Its advantage
|
||||
increases with operand sizes for certain operations, since MPIR in many
|
||||
cases has asymptotically faster algorithms.
|
||||
|
||||
MPIR is free software and may be freely copied on the terms contained in the
|
||||
files COPYING.LIB and COPYING (most of MPIR is under the former, some under
|
||||
the latter).
|
||||
|
||||
|
||||
|
||||
OVERVIEW OF MPIR
|
||||
|
||||
There are five classes of functions in MPIR.
|
||||
|
||||
1. Signed integer arithmetic functions (mpz). These functions are intended
|
||||
to be easy to use, with their regular interface. The associated type is
|
||||
`mpz_t'.
|
||||
|
||||
2. Rational arithmetic functions (mpq). For now, just a small set of
|
||||
functions necessary for basic rational arithmetics. The associated type
|
||||
is `mpq_t'.
|
||||
|
||||
3. Floating-point arithmetic functions (mpf). If the C type `double'
|
||||
doesn't give enough precision for your application, declare your
|
||||
variables as `mpf_t' instead, set the precision to any number desired,
|
||||
and call the functions in the mpf class for the arithmetic operations.
|
||||
|
||||
4. Positive-integer, hard-to-use, very low overhead functions are in the
|
||||
mpn class. No memory management is performed. The caller must ensure
|
||||
enough space is available for the results. The set of functions is not
|
||||
regular, nor is the calling interface. These functions accept input
|
||||
arguments in the form of pairs consisting of a pointer to the least
|
||||
significant word, and an integral size telling how many limbs (= words)
|
||||
the pointer points to.
|
||||
|
||||
Almost all calculations, in the entire package, are made by calling these
|
||||
low-level functions.
|
||||
|
||||
5. Berkeley MP compatible functions.
|
||||
|
||||
To use these functions, include the file "mp.h". You can test if you are
|
||||
using the GNU version by testing if the symbol __GNU_MP__ is defined.
|
||||
|
||||
For more information on how to use MPIR, please refer to the documentation.
|
||||
It is composed from the file gmp.texi, and can be displayed on the screen or
|
||||
printed. How to do that, as well how to build the library, is described in
|
||||
the INSTALL file in this directory.
|
||||
|
||||
|
||||
|
||||
REPORTING BUGS
|
||||
|
||||
If you find a bug in the library, please make sure to tell us about it!
|
||||
|
||||
You should first check the MPIR web pages at http://www.swox.com/gmp/,
|
||||
under "Status of the current release". There will be patches for all known
|
||||
serious bugs there.
|
||||
|
||||
Report bugs to bug-gmp@gnu.org. What information is needed in a good bug
|
||||
report is described in the manual. The same address can be used for
|
||||
suggesting modifications and enhancements.
