9 mins readPython Numbers & Arithmetic Operators
In Plain English
Lua 5.3+ seamlessly integrates 64-bit integers and double-precision floats. In addition to standard math operators, Lua provides floor division (`//`) and exponentiation (`^`).
Deep Dive: How It Works
Floor Division (//): Truncates quotient towards negative infinity (`17 // 5` is `3`).
Exponentiation (^): Power operator (`2 ^ 8` is `256.0`).
Modulo (%): Modulo division (`17 % 5` is `2`).
math Library: Built-in functions like `math.floor`, `math.ceil`, `math.sqrt`, `math.random`.
Core Rules to Remember
Floor Division (//): Performs integer division truncating remainder.
Built-in Exponentiation (^): Native power operator without needing function calls.

Micro Exercise
Compute Modulo and Power
- Calculate `local rem = 100 % 7` and `local cube = 3 ^ 3`.
- Print `"Remainder: " .. rem .. " Cube: " .. cube`.
