bool, string
(u)int, (u)int8, (u)int16, (u)int32, (u)int64, uintptr (uintptr 是指针)
byte, rune(表示字符char)
float32, float64, complex64, complex128 (complex表示复数)
go语言只能强制类型转换,不能隐式转化
package main import ( "fmt" "math/cmplx" "math" ) func elert(){ c:=3+4i fmt.Println(cmplx.Abs(c)) //欧拉公式 //fmt.Println( // cmplx.Exp(1i*math.Pi)+1 //) } //go语言只能强制类型转换,不能隐式转化 func triangle(){ var a,b int =3,4 var c int c = int(math.Sqrt(float64(a * a + b * b))) fmt.Println(c) } func main() { elert() triangle() }
