go语言基础之复数类型

1、复数类型

示例1:

package main //必须有一个main包

import "fmt"

func main() {
	var t complex128 //声明
	t = 2.1 + 3.14i  //赋值
	fmt.Println("t = ", t)

	//自动推导类型
	t2 := 3.3 + 4.4i
	fmt.Printf("t2 type is %T
", t2)

	//通过内建函数,取实部和虚部
	fmt.Println("real(t2) = ", real(t2), ", imag(t2) = ", imag(t2))

}

#执行结果:

t =  (2.1+3.14i)
t2 type is complex128
real(t2) =  3.3 , imag(t2) =  4.4
