# How to convert Int data type to Float in Golang?

• Last Updated : 10 May, 2020

In Golang, the data types are bound to variables rather than the values, which means that, if you declare a variable as int, then you can store only integer type value in it, you cant assign character or string in it unless you convert the data type to required data type.

To convert an integer data type to float you can wrap the integer with float64() or float32.

Example:

 `// Golang program to convert Int data type to Float``package main`` ` `import (``    ``"fmt"``    ``"reflect"``)`` ` `func main() {`` ` `    ``// var declared x as int``    ``var x int64 = 5`` ` `    ``// y is a float64 type variable``    ``var y float64 = float64(x)`` ` `    ``// printing the values of x and y``    ``fmt.Printf(``"x = %d \n"``, x)``    ``fmt.Printf(``"y = %f \n"``, y)`` ` `    ``// to print a float upto a``    ``// specific number of decimal point``    ``fmt.Printf(``"\ny upto 3 decimal = %.3f"``, y)`` ` `    ``// getting the converted type``    ``fmt.Println(``"\n"``, reflect.TypeOf(y))`` ` `}`

Output

```x = 5
y = 5.000000

y upto 3 decimal = 5.000
float64
```

Explanation: Firstly we declare a variable x of type int64 with a value of 5. Then we wrap x with float64(), which converts the integer 5 to float value of 5.00. The %.3f formats the float value upto 3 decimal points.
