Based on this Oracle's documentation:

The NUMBER datatype stores fixed and floating-point numbers. Numbers of virtually any magnitude can be stored and are guaranteed portable among different systems operating Oracle, up to 38 digits of precision.

The following numbers can be stored in a NUMBER column:

  • Positive numbers in the range 1 x 10-130 to 9.99..9 x 10125 with up to 38 significant digits
  • Negative numbers from -1 x 10-130 to 9.99..99 x 10125 with up to 38 significant digits
  • Zero
  • Positive and negative infinity (generated only by importing from an Oracle Version 5 database)

There's also this other documentation which summarizes very well the types and precision for numeric and other data types as well.
