Better `rsqrt`
Replaces the constants Minecraft uses for their functions for calculating the reciprocal square root (aka rsqrt) with more accurate alternatives
Better rsqrt
N.B.: The accuracy benefits of this is negligible at best, so don't expect anything big to happen. This is created purely because I want to, and I can.
Tested to work every version since 1.14 (v1.0.1)
Replaces the constant Minecraft uses in their fast reciprocal square root
(also known as InvSqrt or rsqrt) functions, to yield better accuracy:
| Function | Original Value | More Accurate™ Value |
|---|---|---|
fastInverseSqrt(float) | 0x5f3759df | 0x5f375a86 |
fastInverseSqrt(double) | 0x5fe6eb50c7b537aa | 0x5fe6eb50c7b537a9 |
Since Minecraft only use these functions in rendering, this "fix" should not affect world generation or other functions that rely on the vanilla result to yield expected results.
