Positive scale is the number of significant digits to the right of the decimal
point to and including the least significant digit.
Negative scale is the number of significant digits to the left of the decimal
point, to but not including the least significant digit. For negative scale the
least significant digit is on the left side of the decimal point, because the actual
data is rounded to the specified number of places to the left of the decimal
point. For example, a specification of (10,-2) means to round to hundreds.
