Before filing a bug, please check whether it has been fixed since the
latest release. Search the issue tracker and check that you're running the
latest version of Go:

Run "go version" and compare against
http://golang.org/doc/devel/release.html  If a newer version of Go exists,
install it and retry what you did to reproduce the problem.

Thanks.

What steps will reproduce the problem?
If possible, include a link to a program on play.golang.org.
1. Compile the below code:

package main

import (
        "fmt"
)

func main() {
        fmt.Printf("%v\n", 1.0 / 2)
        i := 2
        fmt.Printf("%v\n", 1.0 / i)
}

What is the expected output?
(Compile error)

What do you see instead?
0.5
0

Which compiler are you using (5g, 6g, 8g, gccgo)?
6g

Which operating system are you using?
Linux

Which version are you using?  (run 'go version')
go version go1.1 linux/amd64

Please provide any additional information below.
I understood the reason but it is surprising. If I use the number literal '1.1' instead
of '1.0', a compile error happens.  This looks inconsistent to me.  I think it is better
to raise an error when dividing a floating-point number literal by an integer.
