Exp Function

  • Article

This page is specific to the Visual Basic for Applications (VBA) Language Reference for Office 2010.

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

Syntax

Exp(number)

The required number argument 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.

Example

This example uses the Exp function to return e raised to a power.

Dim MyAngle, MyHSin
' Define angle in radians.
MyAngle = 1.3    
' Calculate hyperbolic sine.
MyHSin = (Exp(MyAngle) - Exp(-1 * MyAngle)) / 2
