Exp - VBScript

Overview

The Exp function in VB Script calculates the exponential of a given number, which is the value of e (approximately 2.71828183) raised to the power of the input. This function is commonly used in mathematical and scientific applications for calculations involving exponential functions.

Syntax

Exp(number)

Parameters:

  • number: Required. A numeric expression representing the exponent.

Options/Flags

None.

Examples

' Calculate the exponential of 3
Dim result = Exp(3) ' Result: 20.0855369231877

' Calculate the exponential of a variable
Dim x = 2
Dim result = Exp(x) ' Result: 7.38905609893065

Common Issues

  • Invalid Input: The Exp function expects a numeric input. Providing a non-numeric value will result in an error.
  • Overflow: If the exponent is too large (positive or negative), the function will return Infinity or -Infinity.
  • Underflow: If the exponent is too small (positive or negative), the function will return 0.

Integration

The Exp function can be used with other VB Script commands to perform advanced calculations, such as:

  • Calculating the area of a circle with CExp:
Dim radius = 3
Dim area = CExp(radius * radius * Math.PI)
  • Solving exponential equations with Log:
Dim x = 3
Dim result = Log(20.0855369231877) / Log(x)
  • Log: Calculates the natural logarithm of a number.
  • CLng: Converts a numeric expression to a long integer.
  • CInt: Converts a numeric expression to an integer.
