/ (Division Operator)
Description: Divides the first number by the second. The result is always a float; a zero divisor is sent to the Arith handler installed around the code, which chooses the value. A nonzero literal divisor, as below, cannot fail. See Arithmetic Effects.
Both 0.0 and -0.0 request Arith.divideByZero, even when the numerator is NaN or infinity. With a nonzero divisor, IEEE-754 results may include infinity, NaN and signed zero; division does not promise a finite result.
Example
let result = 15 / 3 // result = 5.0result = 15 / 3 // result = 5.0
