|\ | | | | Fixes
| * Fix conflict with __int64_t typedefDavid Lechner2019-06-161-32/+32
| | | | | | | | | | | | On Linux, we get a compile error because __int64_t is defined and included by stdint.h. Double underscores are reseved in C in general and should not be used anyway. Replace with a single leading underscore.
| * add FIXMATH_NO_CTYPE optionDavid Lechner2019-06-162-6/+21
| | | | | | | | | | | | | | | | When compiling with -nostdlib, the functions in ctype may not be available. Add FIXMATH_NO_CTYPE option to replace them with inline functions. Also add unit test to test str functions with this option enabled.
| * clean all unit testsDavid Lechner2019-06-161-0/+3
| | | | | | | | make clean should delete all unit test binary files
| * Add explicit cast in fix16_from_dbl()David Lechner2019-06-161-1/+1
