The current implementation does not give monotonous timing for the following: - mpfr_random (x); for (i = 0; i < k; i++) mpfr_atan (y, x, GMP_RNDN); + mpfr_random (x); for (i = 0; i < k; i++) mpfr_atan (y, x, MPFR_RNDN); for precision 300 and k=1000, we get 1070ms, and 500ms only for p=400! - improve mpfr_sin on values like ~pi (do not compute sin from cos, because of the cancellation). For instance, reduce the input modulo pi/2 in |
