1.1 maekawa 69:
70: * Division routines in the mpz class have changed. There are three classes of
71: functions, that rounds the quotient to -infinity, 0, and +infinity,
72: respectively. The first class of functions have names that begin with
73: mpz_fdiv (f is short for floor), the second class' names begin with mpz_tdiv
74: (t is short for trunc), and the third class' names begin with mpz_cdiv (c is
75: short for ceil).
76:
77: The old division routines beginning with mpz_m are similar to the new
78: mpz_fdiv, with the exception that some of the new functions return useful
79: values.
80:
81: The old function names can still be used. All the old functions names will
82: now do floor division, not trunc division as some of them used to. This was
83: changed to make the functions more compatible with common mathematical
84: practice.
85:
86: The mpz_mod and mpz_mod_ui functions now compute the mathematical mod
87: function. I.e., the sign of the 2nd argument is ignored.
88:
89: * The mpq assignment functions do not canonicalize their results. A new
90: function, mpq_canonicalize must be called by the user if the result is not
91: known to be canonical.
92: * The mpn functions are now documented. These functions are intended for
93: very time critical applications, or applications that need full control over
94: memory allocation. Note that the mpn interface is irregular and hard to
95: use.
96: * New functions for arbitrary precision floating point arithmetic. Names
97: begin with `mpf_'. Associated type mpf_t.
98: * New and improved mpz functions, including much faster GCD, fast exact
99: division (mpz_divexact), bit scan (mpz_scan0 and mpz_scan1), and number
100: theoretical functions like Jacobi (mpz_jacobi) and multiplicative inverse
101: (mpz_invert).
102: * New variable types (mpz_t and mpq_t) are available that makes syntax of
103: mpz and mpq calls nicer (no need for & before variables). The MP_INT and
104: MP_RAT types are still available for compatibility.
105: * Uses GNU configure. This makes it possible to choose target architecture
106: and CPU variant, and to compile into a separate object directory.
107: * Carefully optimized assembly for important inner loops. Support for DEC
1.1.1.2 ! maekawa 108: Alpha, Amd 29000, HPPA 1.0 and 1.1, Intel Pentium and generic x86, Intel
1.1 maekawa 109: i960, Motorola MC68000, MC68020, MC88100, and MC88110, Motorola/IBM
110: PowerPC, National NS32000, IBM POWER, MIPS R3000, R4000, SPARCv7,
111: SuperSPARC, generic SPARCv8, and DEC VAX. Some support also for ARM,
112: Clipper, IBM ROMP (RT), and Pyramid AP/XP.
113: * Faster. Thanks to the assembler code, new algorithms, and general tuning.
114: In particular, the speed on machines without GCC is improved.
115: * Support for machines without alloca.
116: * Now under the LGPL.
117:
118: INCOMPATIBILITIES BETWEEN GMP 1 AND GMP 2
119:
120: * mpq assignment functions do not canonicalize their results.
121: * mpz division functions round differently.
122: * mpz mod functions now really compute mod.
123: * mpz_powm and mpz_powm_ui now really use mod for reduction.
