Golang中的Sub()位用於查找a,b與借位之差,即diff = a-b-借位。這裏的借位必須為0或1;否則,行為是不確定的。要訪問此函數,需要在程序中導入math /bits程序包。無論如何,借款輸出的返回值將始終為0或1。
用法:
func Sub(a, b, borrow uint) (diff, borrowOut uint)
參數:此函數采用uint類型的三個參數,即a,b和借位。借位參數的值為1或0
返回值:此函數返回uint類型的兩個值,即diff和roweOut。此處diff包含a-b-借位的結果,並且roweOut為1或0。
範例1:
// Golang program to illustrate bits.Sub() Function
package main
import (
"fmt"
"math/bits"
)
// Main function
func main() {
// Finding diff and borrowOu
// of the specified numbers
// Using Sub() function
nvalue_1, borrowOut:= bits.Sub(4, 3, 0)
fmt.Println("Diff:", nvalue_1)
fmt.Println("BorrowOut:", borrowOut )
}
輸出:
Diff:1 BorrowOut:0
範例2:
// Golang program to illustrate bits.Sub() Function
package main
import (
"fmt"
"math/bits"
)
// Main function
func main() {
// Finding diff and borrowOut
// of the specified numbers
// Using Sub() function
var a, b, borrow uint = 10, 5, 1
Diff, borrowOut:= bits.Sub(a, b, borrow)
fmt.Println("Number 1:", a)
fmt.Println("Number 2:", b)
fmt.Println("Borrow:", borrow)
fmt.Println("Diff:", Diff)
fmt.Println("BorrowOut:", borrowOut)
}
輸出:
Number 1:10 Number 2:5 Borrow:1 Diff:4 BorrowOut:0
