lets say i do some simple AS3 math and get a Number of 199.  
How can i use a Array with values of “preferred” numbers, compare the 199 to the array and round up or down to the closest value in the array?

var myNumber:Number = 199;  
var myArray = new Array(100,175,190,200);  
var myMatch = 200;  
output.text = myMatch;

I want to round the 199 up to 200(closest match) and have the myMatch = the rounded number from the array.

Thank You!!!
