Types

There are 3 basic data types in Go languages which are:

1. Numbers: numbers are divided into three sub-categories that are:

• Integers: In Golang, there are 4(four) different sizes for both signed and unsigned integers

Data Type	Description
int8	8-bit signed integer, range -128 to 127
int16	16-bit signed integer, range -(2^15) to (2^15)-1
int32	32-bit signed integer, range -(2^31) to (2^31)-1
int64	64-bit signed integer, range -(2^63) to (2^63)-1
uint8	8-bit unsigned integer, range 0 to 255
uint16	16-bit unsigned integer, range 0 to (2^16)-1
uint32	32-bit unsigned integer, range 0 to (2^32)-1
uint64	64-bit unsigned integer, range 0 to (2^64)-1
int	Both int and uint contain same size, either 32 or 64 bit.
uint	Both int and uint contain same size, either 32 or 64 bit.
byte	It is a synonym of uint8.

• Float Numbers

Data Type	Description
float32	32-bit IEEE 754 floating-point number
float64	64-bit IEEE 754 floating-point number

• Complex Numbers

Data Type	Description
complex64	Complex numbers which contain float32 as a real and imaginary component.
complex128	Complex numbers which contain float64 as a real and imaginary component.

2. Booleans

3. Strings
