Phillip Cloud updated ARROW-2177: --------------------------------- Description: Allowing both negative and positive scale makes it ambiguous what the scale of a number should be when it using exponential notation, e.g., {{0.01E3}}. Should that have a precision of 4 and a scale of 2 since it's specified as 2 points to the right of the decimal and it evaluates to 10? Or a precision of 1 and a scale of -1?
