public static E : Number
A mathematical constant for the base of natural logarithms, expressed as e. The approximate value of eis 2.71828182845905.
Availability: ActionScript 1.0; Flash Player 5 - In Flash Player 4, the methods and properties of the Math class are emulated using approximations and might not be as accurate as the non-emulated math functions that Flash Player 5 supports.
This example shows how Math.E is used to compute continuously compounded interest for a 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
