Sam Lantinga 6cfe4f2ba8 Fixed documentation errors in testautomation_math.c 2023-01-03 16:44:00 -08:00
Sam Lantinga 7f23d71b6a Added SDL_modf() and SDL_modff() 
This function is useful for accumulating relative mouse motion if you want to only handle whole pixel movement.
e.g.
static float dx_frac, dy_frac;
float dx, dy;

/* Accumulate new motion with previous sub-pixel motion */
dx = event.motion.xrel + dx_frac;
dy = event.motion.yrel + dy_frac;

/* Split the integral and fractional motion, dx and dy will contain whole pixel deltas */
dx_frac = SDL_modff(dx, &dx);
dy_frac = SDL_modff(dy, &dy);
if (dx != 0.0f || dy != 0.0f) {
    ...
}

Sam Lantinga 63724c113b Removed the vi format comments from the source 
Vim users can use the [editorconfig plugin](https://github.com/editorconfig/editorconfig-vim) to automatically set tab spacing for the SDL coding style.

Clang-Tidy fixes (#6725) 2022-12-01 13:07:03 -08:00
Sam Lantinga 5750bcb174
Update for SDL3 coding style (#6717) 
I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base.

In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted.

The script I ran for the src directory is added as build-scripts/clang-format-src.sh

This fixes:

Sam Lantinga 0a48abc860 Switch header convention from #include "SDL.h" to #include <SDL3/SDLh> 
I ran this script in the include directory:
```sh
sed -i '' -e 's,#include "\(SDL.*\)",#include <SDL3/\1>,' *.h
```

I ran this script in the src directory:
```sh
for i in ../include/SDL3/SDL*.h
do hdr=$(basename $i)
   if [ x"$(echo $hdr | egrep 'SDL_main|SDL_name|SDL_test|SDL_syswm|SDL_opengl|SDL_egl|SDL_vulkan')" != x ]; then
        find . -type f -exec sed -i '' -e 's,#include "\('$hdr'\)",#include <SDL3/\1>,' {} \;
    else
        find . -type f -exec sed -i '' -e '/#include "'$hdr'"/d' {} \;
    fi
done
```

Sam Lantinga 63f307fe1f Remove SDL_config.h from the public headers 
The SDL headers are no longer dependent on the build configuration.

Ozkan Sezer 0b8309da0c renamed SDL PI constants to SDL_PI_D and SDL_PI_F. 2022-11-25 22:35:24 +03:00
Sam Lantinga 199423612c Updated test programs with SDL_M_PI* 2022-11-25 10:57:12 -08:00
Pierre Wendling 6784d84c9d N3DS: Fix -Wformat warnings in tests. 
All warnings were about invalid specifiers. Since U/Sint32 is a long,
using `%d` emits a -Wformat warning.

Pierre Wendling 73d8d02629 Test: Fix Exp base case for Win32. 
Add epsilon to the check.
 2022-08-09 21:39:46 -07:00
Pierre Wendling 6bd3e0b189 Test: Check sqrt and atan against the epsilon. 
On i686-linux, the `sqrt_regularCases` and `atan_limitCases` tests would
fail as the result was not precise enough.
 2022-06-15 23:32:40 +03:00
Pierre Wendling cee47a9ebe Test: Use inexact helper for log10 regular cases. 
On ARMv6, the result is not precise enough for this function.

Pierre Wendling a52b8580f0 Test: Tidy up test descriptions and documentation. 
Test function documentation now lists the input(s) and expected output(s).
Descriptions in TestCaseReference were updated.

Pierre Wendling 4d7f12f6bd Test: Add Atan2 tests to math suite. 2022-06-15 12:05:30 -07:00
Pierre Wendling 8ebe640a36 Test: Change inexact tests to use an epsilon. 
Instead of using `trunc` to check the first ten digits, inexact test now
relies on an epsilon defining an acceptable range for the expected
result to be in.

Pierre Wendling 95f6edb9a5 Test: Refactor trigonometric tests into a helper. 
The precision test of these functions need a special helper, it can also
be used for their arc functions down the line.

Pierre Wendling b06eda55e9 Test: Fix math suite build on Win32. 
The cosine precision test now uses an array of double and the result
gets truncated instead of casted to signed int64.

for failed assertions so the internal counter gets updated properly.

Pierre Wendling 43c22e5d1e Test: Refactor math suite duplicate code. 
Many tests were using the same underlying routine, as such three helper
functions were added:
- A wrapper to test double -> double functions.
- A wrapper to test (double, double) -> double functions,
- A wrapper for range tests on double -> double functions.

The result of NAN tests is now logged.
The SDL_TestCaseReference structure were renamed to be more explicit.

Pierre Wendling a3a852e912 Test: Unrolled the array of cases in math suite. 
On OS/2, `INFINITY` is a `const double` which cannot be used to
instantiate an array.
