reflect.Uint() Function in Golang with Examples Last Updated : 10 May, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report Go language provides inbuilt support implementation of run-time reflection and allowing a program to manipulate objects with arbitrary types with the help of reflect package. The reflect.Uint() Function in Golang is used to get v's underlying value, as a uint64. To access this function, one needs to imports the reflect package in the program. Syntax: func (v Value) Uint() uint64 Parameters: This function does not accept any parameter. Return Value: This function returns the v's underlying value, as a uint64. Below examples illustrate the use of the above method in Golang: Example 1: C // Golang program to illustrate // reflect.Uint() Function package main import ( "fmt" "reflect" ) func sum(args []reflect.Value) []reflect.Value { a, b := args[0], args[1] if a.Kind() != b.Kind() { fmt.Println("??? ????.") return nil } switch a.Kind() { case reflect.Int, reflect.Int8, reflect.Int16, reflect.Int32, reflect.Int64: return []reflect.Value{reflect.ValueOf(a.Int() + b.Int())} case reflect.Uint, reflect.Uint8, reflect.Uint16, reflect.Uint32, reflect.Uint64: return []reflect.Value{reflect.ValueOf(a.Uint() + b.Uint())} case reflect.Float32, reflect.Float64: return []reflect.Value{reflect.ValueOf(a.Float() + b.Float())} case reflect.String: return []reflect.Value{reflect.ValueOf(a.String() + b.String())} default: return []reflect.Value{} } } func makeSum(fptr interface{}) { fn := reflect.ValueOf(fptr).Elem() v := reflect.MakeFunc(fn.Type(), sum) fn.Set(v) } // Main function func main() { var intSum func(int, int) int64 var floatSum func(float32, float32) float64 var stringSum func(string, string) string makeSum(&intSum) makeSum(&floatSum) makeSum(&stringSum) fmt.Println(intSum(1, 2)) fmt.Println(floatSum(2.1, 3.5)) fmt.Println(stringSum("Geeksfor","Geeks")) } Output: 3 5.599999904632568 GeeksforGeeks Example 2: C // Golang program to illustrate // reflect.Uint() Function package main import ( "fmt" "reflect" ) func sum(args []reflect.Value) []reflect.Value { a, b := args[0], args[1] if a.Kind() != b.Kind() { fmt.Println("??? ????.") return nil } switch a.Kind() { case reflect.Int, reflect.Int8, reflect.Int16, reflect.Int32, reflect.Int64: return []reflect.Value{reflect.ValueOf(a.Int() + b.Int())} case reflect.Uint, reflect.Uint8, reflect.Uint16, reflect.Uint32, reflect.Uint64: return []reflect.Value{reflect.ValueOf(a.Uint() + b.Uint())} case reflect.Float32, reflect.Float64: return []reflect.Value{reflect.ValueOf(a.Float() + b.Float())} case reflect.String: return []reflect.Value{reflect.ValueOf(a.String() + b.String())} default: return []reflect.Value{} } } func makeSum(fptr interface{}) { fn := reflect.ValueOf(fptr).Elem() v := reflect.MakeFunc(fn.Type(), sum) fn.Set(v) } // Main function func main() { var stringSum func(string, string) string makeSum(&stringSum) fmt.Println(stringSum("Value_1 : ","Geeks_1")) } Output: Value_1 : Geeks_1 Comment More infoAdvertise with us Next Article reflect.TypeOf() Function in Golang with Examples S SHUBHAMSINGH10 Follow Improve Article Tags : Go Language Golang-reflect Similar Reads reflect.Set() Function in Golang with Examples Go language provides inbuilt support implementation of run-time reflection and allowing a program to manipulate objects with arbitrary types with the help of reflect package.
