Integers and Floats

In Lua, the number type holds all kinds of numeric values. You use numbers to count things, measure values, and do math.

Starting with Lua 5.3, numbers come in two flavors: integers (whole numbers) and floats (numbers with a decimal point).

Let's print a couple of numbers to begin.

An integer is a whole number with no fractional part, like 0, 42, or -7.

When you write a number without a decimal point, Lua treats it as an integer.

• 5 is an integer
• -100 is an integer
