|\ | | | | add #include <stdint.h> to int64.h
| * add #include <stdint.h> to int64.hDavid Lechner2019-12-121-0/+2
|/ | | When using the `gcc -M` option to determine header file dependencies, int64.h causes an error because the types from stdint.h are not defined.

|\ | | | | 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
|/ | | | | | | | | | This fixes the error: implicit conversion from 'float' to 'double' to match other operand of binary expression When the compiler options -fsingle-precision-constant -Wdouble-promotion are set

| * Fix '-Werror=shift-negative-value' for gcc 6Gaëtan Harter2017-09-281-1/+1
|/ | | | | | | | GCC 6 introduced warning for shift on negative value numbers. When F16C is called with a negative number it evaluates FIXMATH_COMBINE_I_M with both the positive and the negative value. Fixes #3
