Q:

ORACLE 10g number datatype

I created a table called employees with one column named salary with data type NUMBER(11) 
and then I entered a value into salary of 12345678901
but in output it values shows like this 1.2345E+10. 
Can anyone explain me what this is exactly?

A:

It is the scientific notation of the number. You may take a look at this article about numeric data types in Oracle.
