# EXP

Syntax

Description of the illustration exp.gif

Purpose

`EXP` returns `e` raised to the `n`th 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 datatype or any nonnumeric datatype that can be implicitly converted to a numeric datatype. If the argument is `BINARY_FLOAT`, then the function returns `BINARY_DOUBLE`. Otherwise the function returns the same numeric datatype as the argument.

See Also: Table 2-10, "Implicit Type Conversion Matrix" for more information on implicit conversion

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
