TrimRight在golang中的定界符后的所有内容

Question

I have a float64 I converted into a string: 30.060671

I'm trying to trim/remove/chomp everything after 30

Some of the things I've tried:

fmt.Println(strings.TrimRight("30.060671", ".([0-9])"))
fmt.Println(strings.TrimRight("30.060671", "."))
fmt.Println(strings.TrimSuffix("30.060671", "."))

Answer 1

One way to do it would be to use strings.Split on the period:

parts := strings.Split("30.060671", ".")
fmt.Println(parts[0])

Another option is to convert to an int first and then to a string:

a := 30.060671
b := int(a)    
fmt.Println(b)
