Datatypes

In Y, every value has a type associated with it. Some types are built into the language, some are user defined. Examples for built-in types are:

• numeric types (e.g. u32, f64, i64)
  • the letter denotes the type of number (e.g., u for unsigned, i for signed integers, and f for floating point numbers)
  • the number denotes the actual size of the underlying number in bits
• characters (char)
• string literals (str)
• boolean values (bool)

These basic types do only provide limited methods or functions to interact with them. However, you can perform certain arithmetic operations on them.

Y is able to infer the types of man variables. In some cases, however, you are required to explicitly declare the type of a variable:

let foo: u32 = 42;
