 # Understanding the structure of Handmade Math
 
-Most of the functions in Handmade Math are very short, and are the kind of functions you want to have inlined. Because of this, most functions in Handmade Math are defined with `HINLINE`, which is defined as `static inline`.
+Most of the functions in Handmade Math are very short, and all are the kind of functions you want to be easily inlined for performance. Because of this, all functions in Handmade Math are defined with `HMM_INLINE`, which is defined as `static inline`.
-
-The exceptions are functions like `HMM_Rotate`, which are long enough that it doesn't make sense to inline them. These functions are defined with an `HEXTERN` prototype, and implemented in the `#ifdef HANDMADE_MATH_IMPLEMENTATION` block.

 Version         | Changes        |
 ----------------|----------------|
+**1.11.1** | Added HMM_PREFIX macro to a few functions that were missing it. |
 **1.11.0** | Added ability to customize or remove the default `HMM_` prefix on function names by defining a macro called `HMM_PREFIX(name)`. |
 **1.10.1** | Removed stdint.h, this doesn't exist on some really old compilers and we didn't really use it anyways. |
 **1.10.0** | Made HMM_Perspective use vertical FOV instead of horizontal FOV for consistency with other graphics APIs. |
