# HIP MATH APIs Documentation
HIP supports most of the device functions supported by CUDA. Way to find the unsupported one is to search for the function and check its description
Note: This document is not human generated. Any changes to this file will be discarded. Please make changes to Python3 script docs/markdown/device_md_gen.py

## For Developers
If you add or fixed a device function, make sure to add a signature of the function and definition later.
For example, if you want to add `__device__ float __dotf(float4, float4)`, which does a dot product on 4 float vector components
The way to add to the header is,
```cpp
__device__ static float __dotf(float4, float4);
/*Way down in the file....*/
__device__ static inline float __dotf(float4 x, float4 y) {
 /*implementation*/
}
```

This helps python script to add the device function newly declared into markdown documentation (as it looks at functions with `;` at the end and `__device__` at the beginning)

The next step would be to add Description to  `deviceFuncDesc` dictionary in python script.
From the above example, it can be writtern as,
`deviceFuncDesc['__dotf'] = 'This functions takes 2 4 component float vector and outputs dot product across them'`
