Example
// A positive and a negative value to demonstrate behavior
type Number NONINT = 12345678.9876
type Number INT = 12345678
Type Number TRY1 = INT.random() // between 0 and 12345677
Type Number TRY2 = NONINT.random() // between 0 and 12345677
// compensate for possible 0 result from INT.random()
Type Number TRY3 = (TRY1 + 1).random()
// DO NOT TRY THIS IT IS LIKELY TO GENERATE AN EXCEPTION
Type Number MayBeNeg = TRY2 - TRY1
Type Number DONT = MayBeNeg.random()
