* testing using ctest

* emove old testing script

* added github workflow CI

* updated CI

* added unit test for macros

* F16() and F16C() are both rounding allways, so fix16_from_dbl should as well

* added tests for strign operations, but these functions are in my opinion unreliable and tests are failing

* removed old unittests

* removed old unittests from cmake

* problem with division using gcc

* improved benchmark

* clarification of problem with division

* attempt to fix

* fixed some undefined behaviors, fixed division

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. :)

Chris Hammond 18a9ad00de Removed 64-bit restriction on linear interpolation functions. Added more test cases and fixed several bugs in the 64-bit arithmetic functions. 
Also added script to run all unit tests.

add #include <stdint.h> to int64.h 
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
 2019-06-17 09:17:19 +03:00
David Lechner 11855068c3 Fix conflict with __int64_t typedef 
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.
 2019-06-16 15:38:23 -05:00
David Lechner ff0a5f69c2 add FIXMATH_NO_CTYPE option 
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.
 2019-06-16 15:38:19 -05:00
David Lechner 108fd93a34 clean all unit tests 
make clean should delete all unit test binary files
 2019-06-16 15:37:41 -05:00
David Lechner 3b7f96f982 Add explicit cast in fix16_from_dbl() 
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
