In the following example, the integer type is converted into a floating point type, the result is calculated, and the result is assigned to a floating point variable:

package main import "fmt" func main() { var sum int = 17 var count int = 5 var mean float32 mean = float32(sum)/float32(count) fmt.Printf("mean 的值为: %f\n",mean) }

The above example executes the output result For:

mean 的值为: 3.400000
