Time is not a number
yourbasic.org/golang
Why doesn’t this compile?
n := 100
time.Sleep(n * time.Millisecond)invalid operation: n * time.Millisecond (mismatched types int and time.Duration)
Answer
There is no mixing of numeric types in Go.
You can only multiply a time.Duration with
- another
time.Duration, or - an untyped integer constant.
Here are three correct examples.
var n time.Duration = 100
time.Sleep(n * time.Millisecond)
const n = 100
time.Sleep(n * time.Millisecond)
time.Sleep(100 * time.Millisecond)
See Untyped numeric constants with no limits for details about typed and untyped integer and floating point constants and their limits.
