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.
Usage
Math.E:Number
Description
Constant; a mathematical constant for the base of natural logarithms, expressed as e. The
approximate value of e is 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
