Definition: Float is short for floating point and is a fundamental (i.e. built into the compiler) type used to define numbers with fractional parts.

The float type can represent values ranging from approximately 1.5 × 10⁻⁴⁵ to 3.4 × 10³⁸ with a precision of 7 digits.

There is also a double.

Numbers without fractional parts can be stored in ints.
