WebArbitrary precision arithmetic could be faster if Emacs had GNU GMP linked to it, with the relevant Emacs Lisp functions added in C. What is the consensus on linking the GNU GMP library to Emacs so that packages such as Emacs Calc (and others) could benefit from using native types (i.e. "mpz_t") rather than reinventing the wheel?

WebGMP adds types ‘Z’, ‘Q’ and ‘F’ for mpz_t, mpq_t and mpf_t respectively. ‘Z’ and ‘Q’ behave like integers.‘Q’ will read a ‘/’ and a denominator, if present.‘F’ behaves like a float. GMP variables don’t require an & when passed to gmp_scanf, since they’re already “call-by-reference”.For example, Web7 Floating-point Functions GMP floating point numbers are stored in objects of type mpf_tand functions operating on them have an mpf_prefix.

WebMay 8, 2010 · Yes, there's a function mpz_set_d that you can use for this purpose: void mpz_set_d (mpz_t rop, double op); The float will be upgraded to a double by C itself and then GMP will turn that into an mpz_t type for you. But you should be aware that mpz_t is an integer type, so you may lose precision. WebThe gmp_int back-end is used via the typedef boost::multiprecision::mpz_int .
