It has a rich set of -functions, and the functions have a regular interface. - -GNU MP 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). - -GNU MP is believed to be faster than any other similar library. Its advantage -increases with operand sizes for certain operations, since GNU MP in many -cases has asymptotically faster algorithms. - -GNU MP is free software and may be freely copied on the terms contained in the -files COPYING.LIB and COPYING (most of GNU MP is under the former, some under -the latter). - - - - OVERVIEW OF GNU MP - -There are five classes of functions in GNU MP. - - 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 GNU MP, 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 GNU MP 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. - - - - ----------------- -Local variables: -mode: text -fill-column: 78 -End:
