I also made some minor changes to `plot' so that its functions would
type more easily. In particular, everything that used to take a list
of vectors now accepts a (Sequenceof (Sequenceof Real)). The 3D
discrete histogram renderers now also accept lists as well as vectors
in the sequence of categories.
For now, in typed/plot functions, optional non-keyword arguments are
required. As soon as Vincent closes PR 13354, I should be able to
uncomment part of a macro in "typed/plot/syntax.rkt" to make them
correctly optional.
I started from tabs that are not on the beginning of lines, and in
several places I did further cleanings.
If you're worried about knowing who wrote some code, for example, if you
get to this commit in "git blame", then note that you can use the "-w"
flag in many git commands to ignore whitespaces. For example, to see
per-line authors, use "git blame -w <file>". Another example: to see
the (*much* smaller) non-whitespace changes in this (or any other)
commit, use "git log -p -w -1 <sha1>".
Although this shouldn't affect document rendering, since
each document is run under a custodian that is shut down,
it simplifies using the document individually to check for
leaks.
Altered TR's random arithmetic testing to generate single-flonums and very small flonums; fails now because of erroneous types
Fixes to sgn, sinh, cosh, and tanh:
* preserve single-flonum-ness
* correct zero sign (-0.0) for negative return values that are smaller than epsilon
* correct behavior with NaN and infinite inputs
This makes it more efficient to plot piecewise functions by drawing each piece with one renderer, and possible to plot functions with discontinuities by using a renderer to draw each continuous piece.
Also, use keywords for `make-pen' and `make-brush'.
Adding `make-pen' and `make-color' creates many conflicts among
teaching libraries, such as `2htdp/image'. These are easy to fix
up in the tree, but adding such obvious names to `racket/draw'
may create other compatibility problems, so we might have to reconsider
the names.
In consultation with Asumu.
plots too small to render margin decorations (i.e. axis and tick labels) now render without them;
plots in frames now initially render with full detail
This change significantly increases the speed of number formatting, making extreme-bounds-tests.rkt run in about 1/4 the time.
Should consider moving these into racket/math, since floor-log/base generalizes order-of-magnitude.
