Revision 7837f0e by Bastien Montagne (master) July 10, 2015, 13:02 (GMT) |
BLI_math 'compare' cleanup & enhancements. 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! |
