Description of the illustration power.gif
Purpose
POWER
returnsn2
raised to then1
power. The basen2
and the exponentn1
can be any numbers,but ifn2
is negative,thenn1
must be an integer.
This function takes as arguments any numeric datatype or any nonnumeric datatype that can be implicitly converted to a numeric datatype. If any argument isBINARY_FLOAT
orBINARY_DOUBLE
,then the function returnsBINARY_DOUBLE
. Otherwise the function returnsNUMBER
.

Purpose
MOD
returns the remainder ofn2
divided byn1
. Returnsn2
ifn1
is 0.
This function takes as arguments any numeric datatype or any nonnumeric datatype that can be implicitly converted to a numeric datatype. Oracle determines the argument with the highest numeric precedence,implicitly converts the remaining arguments to that datatype,and returns that datatype.

Examples
The following example returns the remainder of 11 divided by 4:
SELECT MOD(11,4) "Modulus" FROM DUAL; Modulus ---------- 3
