a7064d5f6a A bunch of typo fixes from Richard Cleis. 2012-06-14 17:20:05 -04:00

a713ca8a8b Added nan?, infinite?, degrees->radians, radians->degrees, exact-round, exact-floor, exact-ceiling, exact-truncate to racket/math 
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

50ad8dac1f When plot-new-window?' is #t, plot' and `plot3d' now create a frame in a new eventspace. This allows plot frames to be displayed programmatically. (Without this change, the frames are unresponsive until the REPL regains control.) 2012-05-25 13:11:46 +09:00

ee95182386 Made (require plot) more obvious in the plot introduction (suggested by Jens Axel Søgaard) 
Mentioned (plot-new-window? #t) early in the introduction

365ee2c70d 1d, 2d and 3d function renderers no longer sample outside the function's bounds 
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.

68e005fb2c racket/draw: make-immutable-{color,brush,pen} => make-{color,brush,pen} 
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.

568828d491 Fixed graphical glitches: 
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

610280225c Added unstable/gui/snip (provides snip-canvas%) and docs 
Changed plot-frame to use snip-canvas%, so resizing the frame resizes the plot; added Escape handler (closes the frame)

47fcdd4916 Sped up floor-log/base and ceiling-log/base, and made them correct on flonum inputs. 
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.

713772959f Clipping lines now uses exact arithmetic. Fixes visual issues with plotting inexact functions at very small scales. Every plot should render correctly at every scale now. 2012-02-01 09:44:47 -07:00

989fcc4c22 Reworked how major and minor ticks are chosen; now isosurfaces3d always shows 3-5 surfaces, and all *-ticks parameters have the same default 
Contour and isosurface 'auto levels reorg
2D contours: z-min = z-max now makes empty plot instead of infinite loop
3D isosurfaces: d-min = d-max now makes empty plot instead of infinite loop
Fixed contracts and corner case on marching squares and cubes functions

Increased timeout on extreme-bounds-tests.rkt
