We use the following terms below: The
<firstterm>scale</firstterm> of a <type>numeric</type> is the
count of decimal digits in the fractional part, to the right of
the decimal point. The <firstterm>precision</firstterm> of a
<type>numeric</type> 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.
