Simplest way to check if a string converted to a number is actually a number in actionscript

Asked 2009-08-06T17:42:04.190

Not sure if this makes sense, but I need to check if a server value returned is actually a number. Right now I get ALL number values returned as strings ie '7' instead of 7.

What's the simplest way to check if string values can actually be converted to numbers?

Put this into any function where you want only numbers to stay
joy_edit1 is a TextInput Object (spark)

//is a number check
if( isNaN(Number(joy_edit1.text)) ) {
  joy_edit1.text = "";
  return void;
}
