EXP

Syntax

Purpose

EXP returns e raised to the nth power, where e = 2.71828183 ... The function returns a value of the same type as the argument.

This function takes as an argument any numeric data type or any nonnumeric data type that can be implicitly converted to a numeric data type. If the argument is BINARY_FLOAT, then the function returns BINARY_DOUBLE. Otherwise the function returns the same numeric data type as the argument.

Examples

The following example returns e to the 4th power:

SELECT EXP(4) "e to the 4th power" FROM DUAL;

e to the 4th power
