Oracle uses a standard, variable-length internal format to store numbers. This internal format can be up to 38 bits in precision.

The number data type can have two qualifiers, such as:

Column number (precision, scale)

Precision represents a valid bit in a number. If precision is not specified, Oracle uses 38 as the precision.

The scale represents the number of digits to the right of the decimal point, with a scale set to 0 by default. If the scale is set to a negative number, Oracle will trade the number to the specified digit to the left of the decimal point.
