# math.Float32frombits() Function in Golang With Examples

Last Updated : 19 Apr, 2020

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 Float32frombits() function which returns the floating-point number corresponding to the IEEE 754 binary representation 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 Float32frombits() function.

Syntax:

`func Float32frombits(a uint32) float32`

Example 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 Float32frombits() function ` `    ``res_1 := math.Float32frombits(2) ` `    ``res_2 := math.Float32frombits(1) ` `    ``res_3 := math.Float32frombits(0) ` `    ``res_4 := math.Float32frombits(223) ` ` `  `    ``// 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:  3e-45
Result 2:  1e-45
Result 3:  0
Result 4:  3.12e-43
```

Example 2:

 `// 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 Float32frombits() function ` `    ``nvalue_1 := math.Float32frombits(3) ` `    ``nvalue_2 := math.Float32frombits(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:  4e-45
Result 2:  7e-44
Sum of Result 1 and Result 2:  7.4e-44
```
