Question

Here is the code I am using in the label function. Some of the values are numbers and some are strings. It works:

private function getLabel (area:AreasVO):String
{
  return "Area Name: " + area.areaName + "  " + area.areaWidth + " X " + area.areaLength + " X " + area.areaHeight;
}

It produces: Living Room 14 x 12 x 9

In the message function, I want to mix some computations and strings…can’t figure it out. The AreasVO has all the measurements as Type:Number So I can do something like this

private function getMessage (area:AreasVO):Number
{
return area.areaWidth x areaLength;
}

That will give me the area of the ceiling or floor…

What I want is to have this returned:

Totals for Living Room: Area of Ceiling = 144, LF of Walls = 64, SF of Walls = 642

When I try something like this:

private function getMessage (area:AreasVO):Number
{
return "Totals for Living Room: Area of Ceiling = " + area.areaWidth x areaLength;
}

I just get error upon error…Numbers as Strings or a bunch of others…How do I do this?

Answer 1

Enclose the bits of math you want to happen within parenthesis like this:

private function getMessage (area:AreasVO):String
{
    return "Totals for Living Room: Area of Ceiling = " + (area.areaWidth * area.areaLength);
}

Or
[In your AreasVO]

public function get computedArea():Number
{
    return length*width;
}

then in the original file

private function getMessage (area:AreasVO):String
{
    return "Totals for Living Room: Area of Ceiling = " + area.computedArea;
}
