Division returns invalid results

[frozentech]

	var environment = map[string]interface{}{
		"percent": 10,
		"amount":  1,
	}
       program, err := expr.Compile("amount * (percent / 100)", expr.Env(environment))

	output, err := expr.Run(program, environment)
	if err != nil {
		panic(err)
	}

	fmt.Println("Result : ", output)

Exprected Result : 0.1
Actual Result: 0

It looks like division is always being done using an integer data type instead of a float

Everything looks correct. If you try this in Go the same result will be.

amount * (percent / 100)
^         ^         ^
int       int       int
