# math.Float64bits() Function in Golang With Examples

Go language provides inbuilt support for basic constants and mathematical functions to perform operations on the numbers with the help of the math package. This package provides Float64bits() function which returns the IEEE 754 binary representation of a with the sign bit of a and the result in the same bit position. So, you need to add a math package in your program with the help of the import keyword to access the Float64bits() function.

Syntax:

`func Float64bits(a float64) uint64`

Example 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) ` ` `  `} `

Output:

```Result 1: 4611686018427387904
Result 2: 4607182418800017408
Result 3: 0
Result 4: 4612361558371493478
```

Example 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) ` ` `  `} `

Output:

```Result 1:  4613937818241073152
Result 2:  4632233691727265792
Sum of Result 1 and Result 2:  9246171509968338944
```
