/*
HandmadeMath.h v1.13.0
This is a single header file with a bunch of useful functions for game and
graphics math operations.
=============================================================================
To disable SSE intrinsics, you MUST
#define HANDMADE_MATH_NO_SSE
in EXACTLY one C or C++ file that includes this header, BEFORE the
include, like this:
#define HANDMADE_MATH_NO_SSE
#include "HandmadeMath.h"
=============================================================================
If you would prefer not to use the HMM_ prefix on function names, you can
#define HMM_PREFIX
To use a custom prefix instead, you can
#define HMM_PREFIX(name) YOUR_PREFIX_##name
=============================================================================
To use HandmadeMath without the CRT, you MUST
#define HMM_SINF MySinF
#define HMM_COSF MyCosF
#define HMM_TANF MyTanF
#define HMM_SQRTF MySqrtF
#define HMM_EXPF MyExpF
#define HMM_LOGF MyLogF
#define HMM_ACOSF MyACosF
#define HMM_ATANF MyATanF
#define HMM_ATAN2F MYATan2F
Provide your own implementations of SinF, CosF, TanF, ACosF, ATanF, ATan2F,
ExpF, and LogF in EXACTLY one C or C++ file that includes this header,
BEFORE the include, like this:
#define HMM_SINF MySinF
#define HMM_COSF MyCosF
#define HMM_TANF MyTanF
#define HMM_SQRTF MySqrtF
#define HMM_EXPF MyExpF
#define HMM_LOGF MyLogF
#define HMM_ACOSF MyACosF
#define HMM_ATANF MyATanF
#define HMM_ATAN2F MyATan2F
#include "HandmadeMath.h"
If you do not define all of these, HandmadeMath.h will use the
versions of these functions that are provided by the CRT.
