Number.MAX_VALUE

Description

The MAX_VALUE property returns the largest representable positive number in ActionScript (1.79769313486231e+308). It is convenient when you want to start with a very large value, as shown in the following Example. Any number greater than MAX_VALUE can't be represented by ActionScript and is therefore considered to be POSITIVE_INFINITY (i.e., Infinity).

Example

Here we are looking for a minimum value in an array. We initialize the minVal variable to MAX_VALUE, knowing that any subsequent value will be less than it:

var myArray = [-10, 12, 99];
var minVal = Number.MAX_VALUE;
for (var thisValue in myArray) {
  if (myArray[thisValue] < minVal) {
    minVal = myArray[thisValue];
  }
}
trace ("The minimum value is " + minVal);
