E (Math.E property)

public static E :
A mathematical constant for the base of natural logarithms, expressed as e. The approximate
value of eis 2.71828182845905.

Example
This example shows how
simple case of 100 percent interest over a one-year period.
var principal:Number = 100;
var simpleInterest:Number = 100;
var continuouslyCompoundedInterest:Number = (100 * Math.E) - principal;
trace ("Beginning principal: $" + principal);
trace ("Simple interest after one year: $" + simpleInterest);
trace ("Continuously compounded interest after one year: $" +
continuouslyCompoundedInterest);
//
Output:
Beginning principal: $100
Simple interest after one year: $100
Continuously compounded interest after one year: $171.828182845905

exp (Math.exp method)

public static exp(x:Number) : Number
