There is no practical limit to the precision except the ones implied by the available memory in the machine GMP runs on. GMP has a rich set of functions, and the functions have a regular interface. Version 6.1.0 is an upstream release fully binary and ABI compatible with the 6.0.0 and 5.x versions. --8<---------------cut here---------------start------------->8--- GMP 6.1.0 release announcement BUGS FIXED The public function mpn_com is now correctly declared in gmp.h. =20=20=20=20 Healed possible failures of mpn_sec_sqr for non-cryptographic sizes for some obsolete CPUs. =20=20=20=20 The option --disable-assembly now disables all inlined asm. =20=20=20=20 Fixed bug affecting mini-gmp's bitwise functions mpz_setbit, mpz_clrbit, and mpz_combit. =20=20=20=20 Various problems related to precision for mpf have been fixed. =20=20=20=20 Fixed ABI incompatible stack alignment in calls from assembly code. =20=20=20=20 Fixed PIC bug in popcount affecting Intel processors using the 32-bit ABI. =20=20=20=20 SPEEDUPS Speedup for Intel Broadwell and Skylake though assembly code making use of new ADX instructions. =20=20=20=20 Square root is now faster when the remainder is not needed. Also the speed to compute the k-th root improved, for small sizes. =20=20=20=20 Improved arm64 support. FEATURES New C++ functions gcd and lcm for mpz_class. =20=20=20=20 New public mpn functions mpn_divexact_1, mpn_zero_p, and mpn_cnd_swap. =20=20=20=20 New public mpq_cmp_z function, to efficiently compare rationals with integers. =20=20=20=20 Support for Darwin in all x86 code, thereby enabling fat builds on Darwin. =20=20=20=20 Support for more 32-bit arm processors. =20=20=20=20 Support for compilation with clang/llvm on more platforms. Caution: GMP triggers mis-compilation bugs in clang for many platforms, such as arm, x86 (32-bit and 64-bit), powerpc, mips. =20=20=20=20 Support for AVX-less modern x86 CPUs. (Such support might be missing either because the CPU vendor chose to disable AVX, or because the running kernel lacks AVX context switch support.) =20=20=20=20 Stack usage trimmed; we believe 512 KiB is now sufficient for any GMP call, irrespective of operand size. =20=20=20=20 Support for NetBSD under Xen; we switch off AVX unconditionally under NetBSD since a bug in NetBSD makes AVX fail under Xen. MISC We now use manufacturers' code names for x86 CPUs, e.g., "haswell" instead of names derived from the commercial brands. =20=20=20=20 Small improvements and better coverage for the test suite. =20=20=20=20 The various FreeBSD problems listed for 6.0.0 affect this release too. =20=20=20=20 Tuned values for FFT multiplications are provided for larger number on many platforms. =20=20=20=20 This release would not have been possible without the continuous work of improvement, revision and refinement by the whole GMP team: Torbj=C3=B6rn Granlund, Niels M=C3=B6ller, Marco Bodrato, and Marc Glisse.
