Below table summarizes the complex numbers. a . Byte b . rune (same as int32) c . uint d . int e . uintptr Syntax to create variable var variableName dataType var variableName dataType = value variableName := value HelloWorld.go package main import "fmt" func main() { var a int = var b uint8 = var c uint16 = var d uint32 = var e uint64 = var f int8 = var g int16 = var h int32 = var i int64 = var k float32 = var l float64 = complex1 := complex ( , ) fmt.Println( "a : " , a); fmt.Println( "b : " , b); fmt.Println( "c : " , c); fmt.Println( "d : " , d); fmt.Println( "e : " , e); fmt.Println( "f : " , f); fmt.Println( "g : " , g); fmt.Println( "h : " , h); fmt.Println( "i : " , i); fmt.Println( "k : " , k); fmt.Println( "l : " , l); fmt.Println( "complex1 : " , complex1); } Output a : 10 b : 11 c : 12 d : 13 e : 14 f : 15 g : 16 h : 17 i : 18 k : 2 l : 2 complex1 : (10+13i) How to access real and imaginary numbers from complex numbers? You can use real and img methods to access the real and complex parts of a number. myComplex := complex(10, 13) real(myComplex) imag(myComplex) HelloWorld.go package main import "fmt" func main() { complex1 := complex ( , ) var realPart = real (complex1) var imgPart = imag (complex1) fmt.Println( "complex1 : " , complex1); fmt.Println( "realPart : " , realPart); fmt.Println( "imgPart : " , imgPart); } Output complex1 : (10+13i) realPart : 10 imgPart : 13
