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.
