Overview
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.
When a regular integer is needed in the program, int should be the default.
byte
byte is unsigned int represented on a byte (uint8).
Indexing operator [] applied to strings return bytes.
Conversion of a byte to string
Conversion of a string to bytes:
bytes := []byte("test")
Conversion of bytes to string:
str := string([]byte{'t', 'e', 's', 't'})
