Exp

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

Syntax: Exp( number )

number
required A Double or any valid numeric expression.

The constant e is approximately 2.718282.

Note

Common Errors

Error When
6 (&H6), Overflow number is greater than 709.782712893384
94 (&H5E), Invalid use of Null number is Null

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
