clean way to distinguish between float and int numbers?

[Av1shay]

Hi
I need to parse *fastjson.Value value to a string, in case of Number type is there an elegant and fast way check if the value is int number or float number?

func parseFastJsonVal(v *fastjson.Value) string {
	switch v.Type() {
        ...
	case fastjson.TypeNumber:
                 // if it's int number i want to return fmt.Sprintf("%d", v.GetInt())
                
                // if it's float i want to return fmt.Sprintf("%v", v.GetFloat64())
	}
	return ""
}

I can do naive stuff like checking explicitly if it's float or if it has a decimal point, but i wonder if there is a fastest way to check it based on the data i already got from parsing the JSON
