|/ | | This library is wonderful, however, it's missing an explicit license in its source code. This adds the text of the MIT license along with the name of the original author. This helps folks like me make sure we follow the license terms when using this library. :)

|\ | | | | 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

|/ | | | | | | | 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
