Course of Raku / Essentials

Data type conversion

So far, we have seen a number of data types that Raku supports. Those were different kinds of numbers (integers, rational numbers, and floating-point numbers), strings, and Boolean type. Each data type has its name in the Raku type system.

Str | String of characters Int | Integer number Rat | Rational number Num | Floating-point number Bool | Logical Boolean

There are more data types that Raku understands. We will see them in the further sections of this course.
