create a struct with a field of type float in go

You can create a struct with a field of type float in Go by defining the field as float32 or float64, depending on your precision needs. Here's an example:

main.go
type Circle struct {
    radius float64
}
42 chars
4 lines

In this example, we've defined a struct called "Circle" with a single field called "radius" which is of type float64. You can create a new instance of this struct and set the value of the radius field, like this:

main.go
myCircle := Circle{radius: 3.14}
33 chars
2 lines

In this example, we've created a new instance of the Circle struct and set the value of the radius field to 3.14.
