Convert integer to floating point in Golang

Question

How to convert integer value to float64 type?

I tried

float(integer_value) 

But that does not work. And can not find the package that does this on Golang.org.

How do I get float64 values ​​from integer values?

Answer 1

No float type. Looks like you want float64 . You can also use float32 if you only need a floating point value with one precision.

 package main import "fmt" func main() { i := 5 f := float64(i) fmt.Printf("f is %f\n", f) } 

Answer 2

For completeness only, here is a link to the golang documentation that describes all types . In your case, these are numeric types:

 uint8 the set of all unsigned 8-bit integers (0 to 255) uint16 the set of all unsigned 16-bit integers (0 to 65535) uint32 the set of all unsigned 32-bit integers (0 to 4294967295) uint64 the set of all unsigned 64-bit integers (0 to 18446744073709551615) int8 the set of all signed 8-bit integers (-128 to 127) int16 the set of all signed 16-bit integers (-32768 to 32767) int32 the set of all signed 32-bit integers (-2147483648 to 2147483647) int64 the set of all signed 64-bit integers (-9223372036854775808 to 9223372036854775807) float32 the set of all IEEE-754 32-bit floating-point numbers float64 the set of all IEEE-754 64-bit floating-point numbers complex64 the set of all complex numbers with float32 real and imaginary parts complex128 the set of all complex numbers with float64 real and imaginary parts byte alias for uint8 rune alias for int32 

This means you need to use float64(integer_value) .
