MOD Function

This was tested on Oracle 11.1.0.6.0 running on Windows XP. The mod function calculates the remainder when you divide the first value by the second:

SQL> select mod(10,7) from dual;

 MOD(10,7)
----------
         3

SQL> select mod(-11,6) from dual;

MOD(-11,6)
----------
        -5

SQL> select mod(9,-5) from dual;

 MOD(9,-5)
----------
         4

SQL> select mod(-8,-3) from dual;

MOD(-8,-3)
----------
        -2

SQL>

The numbers do not have to be integers:

SQL> select mod(4,1.5) from dual;

MOD(4,1.5)
----------
         1

SQL> select mod(6.2,3) from dual;

MOD(6.2,3)
----------
        .2

SQL>

... but I was a bit surprised that the next calculation did not return a division by zero error:

SQL> select mod(2,0) from dual;

  MOD(2,0)
----------
         2
