-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've uploaded the latest code to http://umass.glexia.net/mpf.tar.bz2
Here's a quick rundown of supported functions and operations. The MPF() constructor accepts a string and an optional keyword argument, prec, specifying precision (as a Long). Supported module functions: mpf_add Add two MPF objects mpf_sub Subtract two MPF objects mpf_div Divide two MPF objects mpf_mul Multiply two MPF objects mpf_sqrt Take the square root of an MPF object mpf_neg Get the negative of an MPF object mpf_abs Get the absolute value of an MPF object mpf_pow Raise an MPF object to a power mpf_ceil Round an MPF object to the next highest integer mpf_floor Round an MPF object to the next lower integer mpf_trunc Truncate the decimal portion of an MPF object Operations supported: (note that only MPF objects are supported atm) + - * / ** abs() and - (negative) Attributes: value A tuple of the form (base, sign, whole, decimal) Also, it supports a print() representation. No more finagling with value if you don't want to. Things to come: floor divide, support for other python numbers in the number interface Comments: This wasn't a case of NIH syndrome. I wrote this extension because Decimal simply was not fast enough and the builtin floats didn't provide enough precision for a project. The pre-existing modules were terrible, didn't compile, etc. Necessity, not NIH syndrome. Questions: What features would you like to see? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFG++HqqR5p8HaX4oURAsROAKCfNMxxoa+i0lFWJZPDWH8/lguT5ACfSl7d eYrrkokoCIjuFmnxTW6f4y4= =cZ8M -----END PGP SIGNATURE----- _______________________________________________ Python-3000 mailing list [email protected] http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
