Use: Required

Data Type: Numeric

Double

Description

A Double representing the natural number e raised to the power d. Note that the irrational number e is approximately 2.7182818.

Rules at a Glance

• The maximum value for d is 709.782712893.

• Exp is the inverse of the Log function.

• Because this function can only accept numeric values, you may want to check the value you pass using the IsNumeric function to prevent generating an error.

• This is a Shared member, so it can be used without creating any objects.

VB .NET/VB 6 Differences

• In VB 6, Exp was an intrinsic VB function. In VB .NET, it is a member of the Math class in the System namespace. Hence, in VB .NET, calls to Exp must be prefaced with the Math class name.
