      We use the following terms below:  The
-     scale of a numeric is the
-     count of decimal digits in the fractional part, to the right of
-     the decimal point.  The precision of a
-     numeric is the total count of significant digits in
-     the whole number, that is, the number of digits to both sides of
-     the decimal point.  So the number 23.5141 has a precision of 6
-     and a scale of 4.  Integers can be considered to have a scale of
-     zero.
