murata	e903cb9945	AP_Math: Change mask value to hexadecimal number.	8 years ago
Pierre Kancir	da49149d19	AP_Math: is_equal correct comparison for integer as epsilon doesn't exist. Credit to Kwikius for the right solution	8 years ago
Andrew Tridgell	a8d10e8c2c	AP_Math: added get_random16()	8 years ago
Ricardo de Almeida Gonzaga	481e3a2af6	AP_Math: Fix typos	9 years ago
dgrat	6d3b491c02	AP_Math: Replace is_equal with a type safe template function It makes sense to consider also other floating point types.	9 years ago
dgrat	503867b7dc	AP_Math: Replace safe_sqrt() by template function	9 years ago
dgrat	5deb0e8e03	AP_Math: Replace safe_asin() by template function	9 years ago
Lucas De Marchi	846b4927ec	AP_Math: use if/else chain instead of 2 ternary operators	9 years ago
dgrat	174f899a29	AP_Math: Replace the constrain_* functions by a single template Besides being simpler this reduces ~4k in the binary size for PX4.	9 years ago
Lucas De Marchi	880f130670	AP_Math: fix loss of precision on float addition When using wrap_180_cd() we are adding a small float (180 * 100) to a possibly big number. This may lose float precision as illustrated by the unit test failing: OUT: ../../libraries/AP_Math/tests/test_math.cpp:195: Failure OUT: Value of: wrap_180_cd(-3600000000.f) OUT: Actual: -80 OUT: Expected: 0.f OUT: Which is: 0	9 years ago
dgrat	76362caee0	AP_Math: Replace wrap_* functions with template versions	9 years ago
Andrew Tridgell	6bff07397e	AP_Math: added linear_interpolate() function	9 years ago
dgrat	5148e41c1a	AP_Math: Cleaned macro definitions Moved Definitions into a separate header. Replaced PI with M_PI and removed the M_PI_*_F macros.	9 years ago
dgrat	7c4c8ea579	AP_Math: Remove ROTATION_COMBINATION_SUPPORT This function is not used.	9 years ago
Valmantas Palikša	d4daf19151	AP_Math: Move simple math function implementations to header for better compile time optimization Functions like sq() are better moved to the header file as inline. Compiler can then optimize these out when used in code, this saves cpu cycles with stack push, pop during function calls.	10 years ago
Randy Mackay	46c652e42f	Math: maxf and minf functions	10 years ago
Andrew Tridgell	77a2b4acf6	AP_Math: removed fast_atan	10 years ago
Tom Pittenger	4ec2fb3a9c	AP_Math: Compiler warnings: nuke fast_atan2() per Randy's suggestion, fast_atan2() is no longer necessary over atan2() because only copter uses it and copter is no longer supported on future builds of APM `ccd578664f (commitcomment-11025083)`	10 years ago
Tom Pittenger	6e6f481ecb	AP_Math: compiler warnings: apply is_zero(float) or is_equal(float)	10 years ago
Andrew Tridgell	eca675c556	AP_Math: fix for HAL_SITL rename	10 years ago
Randy Mackay	0392292489	AP_Math: inline is_equal, add is_zero	10 years ago
dgrat	726d7df710	AP_Math: add is_equal to compare floats	10 years ago
Tom Pittenger	a8dda9f2ed	AP_Math: fix compile warnings re float constants	10 years ago
Jonathan Challinger	5f7480b740	AP_Math: change fast_atan2 to use atan2f on fast CPUs	10 years ago
David Dewey	17374ff5e8	AP_Math: fast_atan2 This is 126us per call vs 199us on the AVR. it is accurate to about 0.28 degrees Committed by rmackay9 but contribution is from David Dewey	11 years ago
Randy Mackay	d81b7b507d	Math: add Leonard's fast tan function	12 years ago
Andrew Tridgell	ba83950fc4	libraries: replace constrain() with constrain_float() this makes the type much more obvious. Thanks to Tobias for the suggestion.	12 years ago
Andrew Tridgell	83dc7dbc92	AP_Math: handle NaN in constrain(), returning average this makes it less likely a NaN will propogate	12 years ago
James Bielman	5631f865b2	Update floating point calculations to use floats instead of doubles. - Allows use of hardware floating point on the Cortex-M4. - Added "f" suffix to floating point literals. - Call floating point versions of stdlib math functions.	12 years ago
Andrew Tridgell	38062bbb6d	AP_Math: support some more rotation combinations	12 years ago
Andrew Tridgell	a072afa223	AP_Math: expand some macros into functions this saves some flash	12 years ago
uncrustify	533860dd73	uncrustify libraries/AP_Math/AP_Math.cpp	13 years ago
Andrew Tridgell	58a68c89d9	Math: added a function to combine standard rotations this will allow us to have an overall board rotation plus a per-sensor rotation	13 years ago
Andrew Tridgell	4422486d44	AP_Math: made rotation matrices more C++ thanks to Adam for the suggestion	13 years ago
Andrew Tridgell	9f0cb78f08	AP_Math: re-work quaternion functions to be more C++ like thanks to Adam for the suggestion!	13 years ago
Andrew Tridgell	4d65cda0ea	AP_Math: added quaternion->matrix and earth frame routines this will be used for 3d acceleration	13 years ago
Andrew Tridgell	8abbbe5713	AP_Math: better way of handling safe_sqrt() better to test the result, than predict it	13 years ago
Andrew Tridgell	c7d5f06b21	AP_Math: added quaternion helper functions and a test suite	13 years ago
Andrew Tridgell	16ed8bc8f6	AP_Math: added rotmat <-> euler functions these will make the dcm matrix manipulation easier to understand	13 years ago
Andrew Tridgell	17d16bc8c6	AP_Math: added safe_sqrt() function this function will never return NAN. It will return zero for negative numbers.	13 years ago
Andrew Tridgell	502fbf6e17	AP_Math: added a safe_asin() function this adds range checking to asin()	13 years ago
