Go語言為基本常數和數學函數提供了內置支持,以借助數學包對數字進行運算。該程序包提供了Float64bits()函數,該函數返回帶有a的符號位且結果位於相同位位置的IEEE 754二進製表示形式。因此,您需要借助import關鍵字在程序中添加數學包,以訪問Float64bits()函數。
用法:
func Float64bits(a float64) uint64
範例1:
// Golang program to illustrate how to
// find the IEEE 754 binary representation
package main
import (
"fmt"
"math"
)
// Main function
func main() {
// Finding IEEE 754 binary
// representation of the
// given numbers
// Using Float64bits() function
res_1:= math.Float64bits(2)
res_2:= math.Float64bits(1)
res_3:= math.Float64bits(0)
res_4:= math.Float64bits(2.3)
// Displaying the result
fmt.Println("Result 1:", res_1)
fmt.Println("Result 2:", res_2)
fmt.Println("Result 3:", res_3)
fmt.Println("Result 4:", res_4)
}
輸出:
Result 1:4611686018427387904 Result 2:4607182418800017408 Result 3:0 Result 4:4612361558371493478
範例2:
// Golang program to illustrate how to
// find the IEEE 754 binary representation
package main
import (
"fmt"
"math"
)
// Main function
func main() {
// Finding IEEE 754 binary
// representation of the
// given numbers
// Using Float64bits() function
nvalue_1:= math.Float64bits(3)
nvalue_2:= math.Float64bits(50)
// Sum of the given values
res:= nvalue_1 + nvalue_2
fmt.Println("Result 1:", nvalue_1)
fmt.Println("Result 2:", nvalue_2)
fmt.Println("Sum of Result 1 and Result 2:", res)
}
輸出:
Result 1: 4613937818241073152 Result 2: 4632233691727265792 Sum of Result 1 and Result 2: 9246171509968338944
