A Tour of Go Numeric Constants
Numeric constants are high-precision values.
An untyped constant takes the type needed by its context.
Try printing needInt(Big) too.
package main import "fmt"const ( Big = 1 << 100 Small = Big >> 99)func needInt(x int) int { return x*10 + 1}func needFloat(x float64) float64{ return x * 0.1}func main() { fmt.Println(needInt(Small)) fmt.Println(needFloat(Small)) fmt.Println(needFloat(Big))}
