#include <revolution/os.h>inline void OSu8tof32(u8* in, f32* out);

Pointer to the unsigned 8-bit integer value to convert. |
|
Pointer to a 32-bit floating point value to store. |
None.
Fast converts an unsigned 8-bit integer into a 32-bit floating value in two cycles (using a load and store).
The OSInitFastCast must be called before invoking this function.
In the standard debug builds, this function and all other fast cast functions will not be inline-expanded.
This function takes addresses as arguments to load/store instructions. Taking addresses as arguments ensures that the compiler will reserve space on the stack (rather than forcing the programmer or the inline function to allocate space). The stack-allocated variables will likely be in the cache.
