detect number

Well, I've been searching and stuff, I only found the answer to check if the number contains decimals, well I want to check if the float/string is a number, not a string or anything, anyone have an example or can tell me how to detect if a string/variable is a number?

Didn't work :O

PHP Code:


		
			
function onCreated()
{
  var = "test";
  if (float(var) == var)
    echo(var @ " is a number.");
}

test is a number

That's really weird...

Anywho:

PHP Code:


		
			
if (float(var) != -1 || var == "-1")

I guess when comparing a string to a floating point/integer, it's treated as -1... :/

Why not just use type..

Wiki:
You can check the current type with the type()-function - obj.type() returns 0,1,2,3 for numeric, string, object or array.

NPC Code:



function onCreated()

{

  var = 333;

  if (var.type() == 0)

    echo(var @ " is a number. GG LOL");

}
