numstring is a full-featured Lua library for arbitrary-precision math using strings. It supports massive numbers, exact decimal precision, and scientific notation (e.g., 1e100). Designed for projects where Lua’s native number limits are a bottleneck, numstring gives you the power of big math with pure Lua code — no dependencies, no C extensions.

Big numbers are also used.
