Go's Built-in Types

Go has a rich set of built-in types organized into categories:

• Boolean: bool
• Integer: int, int8, int16, int32, int64 and unsigned variants
• Float: float32, float64
• String: string
• Complex: complex64, complex128

Go provides platform-dependent and fixed-size integer types:

• int / uint — platform size (32 or 64 bit)
• int8…int64 — fixed bit widths
• byte — alias for uint8
• rune — alias for int32, represents a Unicode code point

Use int for general-purpose integers unless you need a specific width.
