Golang 中的 math.Float64from mbits()函数，示例为
Original: https://www.geeksforgeeks.org/math-float64frombits-function-in-golang-with-examples/
Go 语言提供了对基本常量和数学函数的内置支持，以便在数学包的帮助下对数字执行运算。 此软件包提供Float64from mbits()函数，该函数返回与 IEEE 754 二进制表示 a 对应的浮点数，符号位为 a，结果位于相同的位位置。 因此，需要在 IMPORT 关键字的帮助下在程序中添加一个数学包来访问 Float64frombits()函数。
语法：
func Float64frombits(a uint64) float64
示例 1：
// Golang program to illustrate how to find
// the floating-point number corresponding
// to the IEEE 754 binary representation
package main
import (
"fmt"
"math"
)
// Main function
func main() {
// Finding floating-point number corresponding
// to the IEEE 754 binary representation
// of the given numbers
// Using Float64frombits() function
res_1 := math.Float64frombits(2)
res_2 := math.Float64frombits(1)
res_3 := math.Float64frombits(0)
res_4 := math.Float64frombits(23)
// 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)
}

// Using Float64frombits() function
nvalue_1 := math.Float64frombits(3)
nvalue_2 := math.Float64frombits(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)
}
