POWER

Syntax

Purpose

POWER returns n2 raised to the n1 power. The base n2 and the exponent n1 can be any numbers, but if n2 is negative, then n1 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 is BINARY_FLOAT or BINARY_DOUBLE, then the function returns BINARY_DOUBLE. Otherwise the function returns NUMBER.

Examples

The following example returns 3 squared:

SELECT POWER(3,2) "Raised" FROM DUAL;    Raised----------         9

MOD

Syntax

Purpose

MOD returns the remainder of n2 divided by n1. Returns n2 if n1 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
