Use the below function in actionscript 3 to find the nearest or closest number in an array. You need to pass the array and the number as a parameter to the below function
//to call the function pass the array and the number to search
nearestNumber(myArray,7);
//use this function to find the closest or nearest number in the array
private function nearestNumber(myArr:Array, num:Number):Number {
var nearNum:Number;
var oldDifference:Number;
for (var x:int=0; x<myArr.length; x++) {
var newDifference:Number = Math.abs(Number(myArr[x]) - num);
if (newDifference <= oldDifference) {
oldDifference = newDifference;
nearNum = myArr[x];
}
}
return nearNum;
}
