David Lechner	0eead94181	lib/libm: Use __asm__ instead of asm. `asm` is not part of the C standard and causes a complier error when `-std=c99` is used. `__asm__` is the recommended alternative. https://gcc.gnu.org/onlinedocs/gcc/extensions-to-the-c-language-family/alternate-keywords.html Signed-off-by: David Lechner <david@pybricks.com>	2022-11-10 11:36:41 +11:00
Zoltán Vörös	27767aafa2	lib/libm_dbl: Add round.c source code. This code is imported from musl, to match existing code in libm_dbl. The file is also added to the build in stm32/Makefile. It's not needed by the core code but, similar to `c5cc64175b`, allows round() to be used by user C modules or board extensions.	2020-07-21 11:07:19 +10:00

Jim Mussared	580a2656d1	stm32: Use hardware double sqrt on F7/H7 MCUs. Identical to `cd527bb324` but for doubles. This gives a -2.754% improvement on bm_float.py, and -35% improvement on calling sqrt in a loop.	2019-10-10 17:39:32 +11:00
Andrew Leech	57a73973ad	lib/libm_dbl: Add implementation of copysign() for DEBUG builds. This provides a double variant of the float copysignf from libm/math.c which is required for DEBUG=1 builds when MICROPY_FLOAT_IMPL=double	2018-09-20 16:46:19 +10:00
Damien George	0b239d458c	lib/libm_dbl/tanh: Make tanh more efficient and handle large numbers. Prior to this patch tanh(large number) would return nan due to inf/inf.	2018-09-04 16:57:46 +10:00
Damien George	045116551e	lib: Add libm_dbl, a double-precision math library, from musl-1.1.16.	2017-06-28 15:12:04 +10:00
