CarverMath 5.46.0

final class · pocketmine\world\generator\vanilla\carver\CarverMath · source

Single precision and lookup-table math used by the carvers, with the results of Minecraft's Mth: sin/cos come from a 65536-entry float table indexed by a double scaled angle, and every float operation of the Java code is rounded to float32 with f() (PHP only has doubles; a double result of one +, -, * or / of two float32 values rounds to the same float32 value as the float operation).
