* Improve documentation for math
Support empty input for cumsummed
Use runnableExamples
Move some examples to tests
Add more tests
* Update tests/stdlib/tmath.nim
Move some tests to trandom.nim
Move tests into main template where possible
Add test for #17017
* Add more tests for gamma & lgamma
Remove gamma(-1.0) example
Small fixes/changes
* Move more tests into template main()
* Fix typos
* Add edge case examples for copySign
* Error -> Defect for defects
The distinction between Error and Defect is subjective,
context-dependent and somewhat arbitrary, so when looking at an
exception, it's hard to guess what it is - this happens often when
looking at a `raises` list _without_ opening the corresponding
definition and digging through layers of inheritance.
With the help of a little consistency in naming, it's at least possible
to start disentangling the two error types and the standard lib can set
a good example here.
* Fix classify to test for subnormality.
* Minor fix.
* Modified to maintain existing API.
* Minor change.
* Removed 32-bit case since float is always 64-bit.
This fixes some tiny issues with using Nim on 16-bit platforms. Not
entirely sure why the AVR chip I was compiling for with "cpu = avr" was
detected as 16-bit, but that's probably another issue..
* Fix many broken links
Note that contrary to what docgen.rst currently says, the ids have
to match exactly or else most web browsers will not jump to the
intended symbol.
* Prefer relative links for Nim documentation
This is more friendly to those browsing the documentation without
a network connection. The nim-doc package in Debian allows this,
for example.
Also, the domain name being used was not consistent. It could have
been either nim-lang.org or nim-lang.github.io, and those reading
the stable docs could have found themselves suddenly reading the
devel docs instead.
* koch.rst: remove link to nonexistent section
* manual.rst: remove unintended link
cast[T](0) is interpreted as a link to id 0 with text T, so escape
the opening parentheses to display the intended output.
* asyncstreams: replace unintended link with emphasis
* Fix word wrapping
* Resolve things raised in https://github.com/nim-lang/Nim/issues/10081 ?
CDF is a standard ident in all things related to random numbers/sampling,
and full words "cumulativeDistributionFunction" would be silly long, in
this case, IMO. We use lowercase `cdf` to make it not look like a type,
remove all looping from `sample` letting callers do it. Besides just
side-stepping any `sampleSize` name choice, callers may want to filter
out samples anyway which this makes slightly simpler.
Also add two variants of `cumsum`, value return and in-place update
distinguished by the var-ness of the first argument. Add tests for
`int` and `float` for both `cumsum` and the new `sample`. (The sample
tests exercise the value return mode of `cumsum`.)
Functionality pre-this-PR `sample(a, w)` is now the almost as simple
`for i in 0..<n: sample(a, w.cumsum)`, but this new code factoring is
almost surely better. The statistical tests pass, as before.
* Address Araq comment in https://github.com/nim-lang/Nim/pull/10084
We can always add in some `var` version later if desired to save
memory, but this change now at least firms up the `sample` interface.
* Rename `cumsum` -> `cumsummed` to honor NEP1 style. Re-instate `cumsum` as
the in-place transformation. Test both in `tests/stdlib/tmath.nim` and use
`cumsummed` in the example code for sample since that's a simpler example.
* Fix requests from https://github.com/nim-lang/Nim/pull/10084 :
example in lib/pure/math.nim and comment whitespace in lib/pure/random.nim
