e exponential functione where e is known as Euler's number and has the value 2.718281828459045... appears many times in the description of natural phenomena. E.g. radioactive decay, population growth and the normal (bell shaped) curve used in statistical applications are all described using this function. The value of the e series can be approximated by the series Write code to calculate the value of e to any value of x the user will choose (set reasonable limits). And allow for the user to compare two different values of x for accuracy purposes (% accuracy difference)
