Go Datatypes

Info

Every not declared variable is 0 by default!

Literals

Note

Literals can have differenct Base, like 0x for Hexadecimal, 0b for Binary, 0o for Octal, etc.

Type	Example
Integer	14, 0b, 0o (decimal, binary, octal)
Float	3.14, 1.6e-10
Rune	a, \141, \u0061, \U00000061, \n, \t, \

Bitshifting

1 << 10 // 1024
10 >> 1 // 5

Integer Numeric Types

Note

For general purpose use int

Type	min	max	size
int8	-128	127	8 bit
int16	-32768	32767	16 bit
int32	-2147483648	2147483647	32 bit
int64	-9223372036854775808	9223372036854775807	64 bit
uint8	0	255	8 bit
uint16	0	65535	16 bit
uint32	0	4294967295	32 bit
uint64	0	18446744073709551615	64 bit

var a int = 14
var b int8 = 14
var c uint8 = 14

Floating Point Numeric Types

Type	min	max	size
float32	1.2E-38	3.4E+38	32 bit
float64	2.2E-308	1.7E+308	64 bit

var a float = 3.14
var b float32 = 3.14
var c float64 = 3.14

Boolean

var b bool
b = true
b = false
