Math Functions

Mathematical functions.

1. math.abs

   `math.abs` returns the absolute value of a number in Lua 5.4. Preserves the integer/float subtype, handles math.mininteger safely, coerces numeric strings.

   math.abs(x)
2. math.ceil

   math.ceil rounds a number up to the smallest integer greater than or equal to it in Lua 5.4, with notes on integer/float subtypes and negative values.

   math.ceil(x)
3. math.floor

   Round a number down to the largest integer less than or equal to it, with integer-vs-float return behavior in Lua 5.4.

   math.floor(x)
4. math.max

   math.max returns the largest of two or more numbers in Lua 5.4, with integer and float subtype rules, type coercion, and edge-case behavior.

   math.max(x, ...)
5. math.min

   math.min returns the smallest of one or more numeric arguments in Lua 5.4. Covers syntax, return type, NaN behavior, infinity, and zero-arg errors.

   math.min(x [, ...])
