  • 4cb88df705 cleanup and reorganize code for mathematical constants Fredrik Johansson 2008-10-04 14:31:56 +00:00
  • 2087bcbf56 Optimized Glaisher's constant. Computation to 3000 dps is now about 4x faster. Fredrik Johansson 2008-10-04 13:02:57 +00:00
  • c804271d20 Streamlined the implementation of Khinchin's constant. With previous improvements to Bernoulli number computation, and with gmpy, the example on the mpmath web site for computing 6000 digits takes 4 minutes instead of 8 hours. Fredrik Johansson 2008-10-04 12:36:39 +00:00
  • d9c6d7319f attempting some cleanup for hypergeometric functions: moved computational code to a separate module. also improved accuracy of erfc for ridiculously large arguments Fredrik Johansson 2008-10-04 11:29:56 +00:00
  • c6b85949a3 Added a function mpf_perturb, to simplify code that needs to calculate x + O(x^2) or x + O(x^3) with directed rounding for small x. Using this for (so far) exp, log, sin, cos, sinh, cosh, atan. This fixed bugs in exp, sinh, cosh for which tests have been written. Fredrik Johansson 2008-10-03 12:00:37 +00:00
  • 5e45936c16 Implemented Taylor series + caching for atan, giving speedups around 3-4x and up to 10x. Also rewrote Newton algorithm for atan to use fixed-point operations. The caching is currently done up to a huge precision; maybe with more precise precision management in atan_newton, this limit could be reduced. Also optimized log_taylor a bit.

  • ed5941724d Changed test_matrices so it does not define test_matrix_numpy if numpy is not there. Mario Pernici 2008-09-30 16:09:05 +00:00
  • 3819c16c9d make sure log_newton takes advantage of exp_series2, giving a ~2x speedup at huge precision (> 10000 digits) when gmpy is used. log should now have the same asymptotic speed as exp, rather than being slightly slower Fredrik Johansson 2008-09-30 15:28:34 +00:00
  • c8c0e7f8ba use Taylor series with caching to compute log at low-to-moderate precision (~< 50-100 digits, depending on whether python or gmpy is used). together with some other streamlining, this leads to log becoming around twice as fast (!) Fredrik Johansson 2008-09-30 14:52:00 +00:00
