Bodiless function in Golang

Question

Reading the source code of math/floor.go, starting from line 13, I read some code like this:

func Floor(x float64) float64

func floor(x float64) float64 {
          


        

Answer 1

In my case I had "../../../pkg/mod/golang.org/x/tools@v0.0.0-20190814235402-ea4142463bf3/go/ssa/interp/testdata/src/fmt/fmt.go:3:6: missing function body" error!

and it was because I used fmt without importing it so my IDE imported the wrong package

I fixed it by removing the fmt import and just importing "fmt"
