12. Floats

Float Type

  • float types are used to represent numbers with decimal value.

  • Go provides two sizes of floating-point numbers, float32 and float64.

main.go
var myFloat float64
myFloat = 3.14

Declaring Floats

Floats are declared using one of the following ways:

main.go
var f float32 = 20.6
var h float64 = 40.2
var h = 40.2
h := 40.2

If we are not specifying type like in 3rd and 4th declaration, it will default to float64

Zero value for float is 0.0
