title: I see a value 1E19 on my Oracle table with number column
body: <p>I see a value 1E19 on my Oracle table with number column. When I try to insert this value to another column marked number(20,5), it fails. If I see the length, it says 1E19 has a length of 19, so that's the reason for the failure (>15).
  So is the value of 1E19 = 1 followed by 18 zeros. How do i see the literal value in Oracle?</p>
