2016-05-17	C99/C++11: replace deprecated finite() by isfinite().	Brecht Van Lommel

2015-07-10	BLI_math 'compare' cleanup & enhancements.	Bastien Montagne
	This commit: * Adds a 'compare_ff' function for absolute 'almost equal' comparison of floats. * Makes 'compare_vxvx' functions use that new 'compare_ff' one. * Adds a 'compare_ff_relative' function for secured ulp-based relative comparison of floats. * Adds matching 'compare_vxvx_relative' functions. * Adds some basic tests for compare_ff_relative. See https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/ Note that we could replace our python/mathutils' EXPP_FloatsAreEqual() by BLI's compare_ff_relative (using a very small absolute max_diff), but these do not have exact same behavior... Left a comment there for now, we can do it later if/when we are sure it won't break anything!

2015-04-21	Math Lib: handling bits handling into own file	Campbell Barton

2015-01-31	Comment for math defines, also add M_PI_4	Campbell Barton

2014-12-27	Fix T43034: beautify-fill leaves zero area tri's	Campbell Barton

2014-11-22	Math Lib: add constant: M_SQRT1_3 1/sqrt(3)	Campbell Barton

2014-11-11	Avoid calling powf with integer exponent in more places	Sergej Reich
	Move powX functions from particle code into math library and use them.
2014-10-10	Code cleanup: Fix silly duplication of typecheck and swap macro	Sergey Sharybin

2014-09-30	Use native float math functions for MSVC12	Sv. Lockal
	`double` surrogates are slow (e.g. pow is 2x slower than powf), and MSVC12 supports fp-math functions from C99.
2014-08-14	remove MAXFLOAT define	Campbell Barton

2014-08-07	Cleanup: Remove special code for Visual Studio 2008.	Thomas Dinges
	Goodbye VC2008, it has been a pleasure (more or less) :D SCons / CMake cleaenup will follow. Differential Revision: https://developer.blender.org/D715
2014-08-02	Make CHECK_TYPE_NONCONST macro portable	Campbell Barton
	also replace __typeof -> typeof
2014-05-13	Fix compilation error with debug SCons	Sergey Sharybin
	For some reason SCons defines _DEBUG, not DEBUG as mathutils was expecting it to be. Made it so mathutils checks for NDEBUG which mimics BLI_assert define.
2014-04-19	Math Lib: add shell_v3v3_normalized_to_dist and v2 version	Campbell Barton
	bypass angle calculation to avoids (asin, sqrt, cos).
2014-04-19	Math Lib: add rotation_between_vecs_to_mat3	Campbell Barton
	- behaves like rotation_between_vecs_to_quat - avoids calling sin,cos calls (approx 1.6x faster).
2014-04-11	Math Lib: use less strict epsilon with BLI_ASSERT_UNIT_QUAT	Campbell Barton
	was causing issues with pointcache
2014-04-05	Math Lib: add power of 2 min/max for unsigned ints	Campbell Barton

2014-03-20	Math Lib: add angle_qt functions	Campbell Barton

2014-02-15	Compile fix for 004decc1d940...	Thomas Dinges

2014-02-15	Code cleanup: warnings	Campbell Barton

2014-01-15	Math Lib: add iroundf function for: (int)floorf(a + 0.5f)	Campbell Barton

2014-01-03	Code Cleanup: WIN32 defines, check for _MSC_VER instead of !FREE_WINDOWS	Campbell Barton

2014-01-03	Fix :I broke the build for MSVC 2008 this fixes it	Martijn Berger

2014-01-03	Fix T37987: MSVC 2013 has C99 headers and warns for out define hypot _hypot ↵	Martijn Berger
	for good reason it seems
2013-12-07	Util Macros: reduce multiple access & conversion for CLAMP/CLAMPIS/ABS	Campbell Barton

2013-12-05	Code Cleanup: use strict flags for math lib, add inline declarations	Campbell Barton

2013-11-30	Woo Hoo. First git commit.	Alexandr Kuznetsov
	Changes for VC2013 Now, I can build Blender with VC2013 with Cycles, Collada, OpenExr,OpenImageIO disabled. Also, you need VC2008 sp1 installed to make old libs compatible.
2013-11-26	Math library: minor additions sqrtf_signed and copy_v2_fl2	Campbell Barton

2013-09-06	rename positive_mod to mod_i, make it work with nagative numbers (matching ↵	Campbell Barton
	pythons modulo), and use in a few more places. allow mesh-checker-deselect to have a negative offset.
2013-09-05	add positive_mod() utility function.	Campbell Barton

2013-08-13	use __builtin_nanf with gcc and clang.	Campbell Barton

2013-08-13	Moved NAN_FLT define to BLI_math, this may come in useful.	Lukas Toenne

2013-05-08	add in asserts when rv3d->viewmatob, rv3d->persmatob are not initialized.	Campbell Barton
	This is often hard to spot since in many cases it works correctly even when not initialized but may still fail in other situations.
2013-04-25	Fix part of #34640: colors darkening when using the vertex paint blur tool.	Brecht Van Lommel
	The problem was that vertex colors only have 8 bits of precision, and integer division always rounds down, so after some color blending iterations everything gets darker. Instead use integer division that behaves like round() instead of floor() for blending operations.
2013-03-13	attempt to quiet warnings for gcc4.2	Campbell Barton

2013-03-12	use gcc warning -Wredundant-decls, exposes some odd/duplicate declarations ↵	Campbell Barton
	which have been removed.
2013-02-19	internal: increase error threshold for normalize assert since normals ↵	Campbell Barton
	converted from shorts are not always exactly unit length.
2013-02-19	make asserts that check for unit length vectors into a macro.	Campbell Barton
	this was really not nice logic to try to fit into an assert.
2013-01-25	Fix warnings about undefined _POSIX_C_SOURCE with gcc 4.2 on Mac.	Brecht Van Lommel

2013-01-25	header cleanup, include BLI before BKE, also use bool for ntreeShaderExecTree	Campbell Barton

2013-01-25	Do not redefine math functions for floats if compiler complies with C99 or ↵	Sv. Lockal
	POSIX.1-2001 This is useful for gcc which does not define sqrtf/powf/... functions with preprocessor and therefore always used sqrt/pow/... Float functions are generally 20-50% faster than their equivalents for double type.
2012-11-23	Patch [#33196] Warning Fixes 11-16-2012	Jason Wilkins
	* MEM_CacheLimitier - Size type to int conversion, should be safe for now (doing my best Bill Gates 640k impression) * OpenNL CMakeLists.txt - MSVC and GCC have slightly different ways to remove definitions (DEBUG) without the compiler complaining * BLI_math inlines - The include guard name and inline option macro name should be different. Suppressed warning about not exporting any symbols from inline math library * BLI string / utf8 - Fixed some inconsistencies between declarations and definitions * nodes - node_composite_util is apparently not used unless you enable the legacy compositor, so it should not be compiled in that case. Leaving out changes to BLI_fileops for now, need to do more testing.
2012-10-23	rename api functions...	Campbell Barton
	- minf, maxf, mini, maxi --> min_ff, max_ff, min_ii, max_ii
2012-09-20	code cleanup: remove unused macros, commet some which may be useful later - ↵	Campbell Barton
	or good to keep for completeness. quieted some warnings and add flags -Wmissing-include-dirs and -Wno-div-by-zero to cmake/gcc
2012-09-08	style cleanup	Campbell Barton

2012-08-26	make SWAP macros typesafe using CHECK_TYPE macro.	Campbell Barton
	Its unlikely you want to do short -> int, int -> float etc, conversion during swapping (if its needed we could have a non type checking macro). Double that the optimized assembler outbut using SWAP() remains unchanged from before. This exposed quite a few places where redundant type conversion was going on. Also remove curve.c's swapdata() and replace its use with swap_v3_v3()
2012-05-31	math lib changes from tomato	Campbell Barton

2012-05-27	code cleanup: defines with braces - end with '(void)0' so callers must end ↵	Campbell Barton
	with ';' like normal function. ... without this some editors dont parse the source so well.
