Standard mathematical library — math.*
Translated from src/lmathlib.c (Lua 5.4.7, 782 lines, 28 functions).
The PRNG is xoshiro256** operating on four 64-bit words. In C the
implementation has two code paths (64-bit integers vs two 32-bit halves);
Rust always has u64, so only the 64-bit path is kept.
Deprecated compat functions guarded by LUA_COMPAT_MATHLIB (cosh, sinh,
tanh, pow, frexp, ldexp, log10, atan2) ship in the default lua5.3.6 build
and are registered only under the 5.3 backend (luaopen_math gates them on
LuaVersion::V53); they remain absent in 5.4/5.5. atan2 is an alias of
the existing math_atan. See specs/followup/5.3-math.md.
