Inconsistencies ( return values )

[JustBreathe]

Stefan: Seems like your post was deleted.

( talked about converting to float and bool )

Couldn't you work it out with type() ?

PHP Code:

function eval( var )
  {
  switch( var.type() )
    {
    case 0:
      return var != false;
    case 1:
      return var != "";
    case 2:
      return var != null;
    case 3:
      return true; // ... Just saying it has a type array means it exists!
    }
  }
