* Make sure that multivariate_normal() uses the standard_normal() method ↵Robert Kern2008-02-122-1865/+1489
| | | | rather than the function so as to use the same consistent state.

* Fix #484: random state not portable between 32-bit and 64-bit architecturescookedm2007-04-022-2277/+2342
| | | | | The random state now uses a uint32 array on both architectures. It should also handle old pickles.
* Fixes #488. In rk_interval, use rk_random if the interval size is less than ↵cookedm2007-04-021-0/+8
| | | | | | | 2**32. For 64-bit machines, this means results will agree with 32-bit machines, and will be faster for these interval sizes (one less rk_random evaluation).
