Method definition usage Analysis in Go language _golang

This example describes the definition of a method in the go language. Share to everyone for your reference. The specific analysis is as follows:

In fact, you can define arbitrary methods for any type in the package, not just the struct body.
Methods cannot be defined on types or underlying types that come from other packages.

Copy Code code as follows:

Package Main
Import (
"FMT"
"Math"
)
Type Myfloat float64
Func (f myfloat) Abs () float64 {
If f < 0 {
return Float64 (-f)
}
return float64 (f)
}
Func Main () {
F: = Myfloat (-math. SQRT2)
Fmt. Println (F.abs ())
}
