Types and Operators

Types

Calvin supports 14 different basic types, and arrays and references of those types. Many of those 14 types are aliases for another type or are different sizes of another type. At its core, Calvin supports integral data types, and floating-point data types.

Table of Types

Size (bytes)	Integral	Real	Complex
1	bool, char, u8, i8
2	u16, i16
4	u32, i32	r32	x32
8	u64, i64	r64	x64

Notes:

• i is for signed integers
• u is for unsigned integers
• values are never implicitly cast
• a reference cast will treat a variable as the cast type without any other type conversion

Other Type Keywords

• const: the modified variable is constant
• var: the type of the variable is inferred by the compiler
