EXP

Returns e raised to the specified power (exponent), where e=2.71828183. For example, EXP(2) returns 7.38905609893065. You might use this function to analyze scientific and technical data rather than business data. EXP is the reciprocal of the LN function, which returns the natural logarithm of a numeric value.

Syntax

EXP( exponent )

The following table describes the argument for this command:

Argument	Required/ Optional	Description
exponent	Required	Numeric datatype. The value to which you want to raise e. The exponent in the equation e^value . You can enter any valid transformation expression.

Return Value

Double value.

NULL if a value passed as an argument to the function is NULL.

Example

The following expression uses the values stored in the Numbers port as the exponent value:

EXP( NUMBERS )

NUMBERS	RETURN VALUE
10	22026.4657948067
-2	0.135335283236613
8.55	5166.754427176
NULL	NULL
