**Description:**

The mathematical constant

`, also called Euler's constant, is the base of the`*e*`Exp`and`Log`and is an irrational and transcendental number. The value of`to twenty significant figures is:`*e*`2.7182818284590452354`. The required`argument can be any valid numeric expression within range of the function. If`*number*`is too large,`*number*`returns infinity. If`**Exp**`is too small,`*number*`returns zero (`**Exp**`0.0`). If`is zero,`*number*`1.0`is returned. The exact limit on`is based on the math processor.`*number***Examples:**

'Compute Continuous Compound Interest

Dim a As Double

Input "Please enter the initial investment (principal amount): "; p

Input "Please enter the annual interest rate (as a decimal): "; r

Input "Please enter the number of years to invest: "; t

a = p * Exp ( r * t )

Print ""

Print "After";t;" years, at an interest rate of"; r * 100; "%, your initial investment of"; p; " would be worth";a

The output would look like:

Please enter the initial investment (principal amount): 100 Please enter the annual interest rate (As a decimal): .08 Please enter the number of years To invest: 20 After 20 years, at an interest rate of 8%, your initial investment of 100 would be worth 495.3032424395115
