Exp function

Returns the power exponent of e(the base of natural logarithm).

Exp(number)

The number argument can be any valid numeric expression.

Description

If the number argument exceeds 709.782712893, an error occurs. The value of constant e is about 2.718282.

Attention The Exp function completes the inverse of the Log function and is sometimes cited as a counter number form.

The following example uses the Exp function to return the power of E:

Dim MyAngle, MyHSin  Defines an angle in radians. MyAngle = 1.3        'calculates the sine of a hyperbolic curve.MyHSin = (Exp(MyAngle) - Exp(-1 * MyAngle)) / 2
