Integers are designated by the following pre-declared type identifiers:

Unsigned integers: uint8 (or byte), uint16, uint32 (or rune), uint64.
Signed integers: int8, int16, int32, int64.
Machine-dependent integers: uint, int and uintptr. int for example can be 4 bytes or 8 bytes long, depending on the underlying architecture.

When a regular integer is needed in the program, int should be the default.

byte is unsigned int represented on a byte (uint8).

A single byte can be converted to string as follows:

var b byte = 65 // decimal ASCII for "A"
str := string(b) // str is "A"

The following expression converts a string to a slice of bytes:

bytes := []byte("test")

The following expression converts a slice of bytes to string:

str := string(bytes)
