Numeric literals come in different numeric kinds. A number written as 22 has no decimal point or fractional part, so it is classified as an integer. Integers store whole numbers and are used for counting, indexing, and whole-number arithmetic. The other data types listed behave differently: a boolean holds true or false; a string stores a sequence of characters (even if those characters look like a number, like "22"); a float (or floating-point number) stores numbers with a fractional part, such as 22.0 or 3.14. If you want a floating-point version of this literal, you’d write 22.0 or use scientific notation like 2.2e1. In short, 22 is an integer.
