# Exp Function

Returns a Double specifying e (the base of natural logarithms) raised to a power.

Syntax

Exp( number )

The required numberargument is a Double or any valid numeric expression.

Remarks

If the value of number exceeds 709.782712893, an error occurs. The constante is approximately 2.718282.

Note:  The Exp function complements the action of the Log function and is sometimes referred to as the antilogarithm.

## Query examples

Expression

Results

SELECT Exp(2) AS Expr1 FROM ProductSales GROUP BY Exp(2);

Returns the value specifying "e(2.718282)" raised to the power of "2" and displays the result in column Expr1.

SELECT Exp(quantity) AS ExpValue FROM ProductSales;

Returns the value specifying "e(2.718282)" raised to the power of data values in the column "quantity". Returns the value specifying "e(2.718282)" raised to the power of data values in the column "quantity" and displays the results in the column "ExpValue".
