John Benediktsson fc5f9451e8 random: implement random for assocs. 2012-10-03 10:08:08 -07:00
Doug Coleman afb2a6eabb random: Bump up the random unit tests from 50k to 500k. At 50k, pareto doesn't have enough samples to get the right std. At 500k, it should never fail again.. 2012-08-16 14:14:08 -07:00
John Benediktsson 676cc18215 random.data: make constants available to random.data. 2012-08-04 19:17:56 -07:00

Doug Coleman cfdbf02a9a random: More leeway for pareto unit test. Python's pareto distribution behaves the same, with a wide variance. Maybe both are busted, or is that just expected from pareto? Fixes #564. 2012-07-26 12:19:21 -07:00
Doug Coleman 46c5d64251 random: Add random-integers and random-units words. 2012-06-20 21:42:15 -07:00

Doug Coleman 6686cae347 random: Add random-unit word. 1 random-unit - is the same distribution, as Joe pointed out, so remove that. Use random-unit in librarie. 2012-03-30 18:04:45 -07:00
John Benediktsson b23f3f8d56 random: 1 swap - was redundant. 2012-03-30 17:57:40 -07:00
John Benediktsson 1e7382b893 random: gauss-random-float is just normal-random-float. 2012-03-30 17:55:18 -07:00
John Benediktsson 1a8e52379a random: adding lognormal, exponential, weibull, pareto, gauss, and beta distributions. 2012-03-30 17:33:13 -07:00
Joe Groff 943596575a use radix literals 2011-11-23 19:03:40 -08:00
Joe Groff 41fe611dda random.unix: roll back type assertions 
Probably don't really make much difference and are invalid in apps that deploy with io level 2 or lower.
 2011-11-16 17:29:46 -08:00
Joe Groff 02df268261 random: don't assume random-bytes is a byte-vector 
It's not anymore.
 2011-11-16 10:03:42 -08:00
Joe Groff 1d4660c7ec random: go faster 
* Use int <ref> instead of 4 >le
* Inline sequences:push-all
* Types, hints, inlines
Re: #328

Joe Groff 8cf18d1a82 remove BSD,solaris,etc. misc platform support code 2011-11-02 17:13:51 -07:00
Doug Coleman 94db86a6db Make "foo.private" require load foo instead. 
Move require from vocabs.loader to vocabs. Update everything.
Fixes #201.

John Benediktsson 37deaec528 random: random integers is 90% faster. 2011-10-14 18:52:41 -07:00
John Benediktsson 950f1e1c04 random: be> is faster (and they are random anyway)... 2011-10-11 22:31:21 -07:00
John Benediktsson afc07c0e05 io.binary: make le> and be> faster (20% and 75%, respectively). 
Removed primitive byte-array>bignum and digit_stream_to_bignum from vm/.

John Benediktsson 4f42c72012 specialized-arrays: performed some cleanup. 
Specifically,
    •   Created >c-array to be replacement for >T-array.
    •   Created cast-array to be generic replacement for all T-array-cast words.
    •   Created c-array@ to be generic replacement for T-array@ words.
    •   Replaced usages of <T-array> with T <c-array>
    •   Replaced usages of <direct-T-array> with T <c-direct-array>
    •   Replaced usages of >T-array with T >c-array
    •   Replaced usages of T-array-cast with T cast-array
    •   Replaced usages of malloc-T-array with T malloc-array.
    •   Removed malloc-T-array.
    •   Removed T-array-cast.
    •   Removed T-array@.
    •   Removed >T-array.

I also added (but didn't change any code to use):
    •   T c-array-type, returns T-array
    •   T c-array?, returns T-array?
    •   c-array{ T ... }, returns T-array{ ... }

Bootstraps just find on Mac OS X.  Also `load-all test-all` works for me.

Joe Groff 2bd6de9a02 slots: pre-create the "at", "nth", and "global" slots to make deterministic the currently nondeterministic ambiguity between accessors:change-* and assocs:change-at, sequences:change-nth, and namespaces:change-global 2011-09-19 10:03:43 -07:00
Joe Groff 8f6c6e5691 random: rewrite normal-random-float to be more readable 2011-09-09 18:13:17 -07:00
