Waddayamean "Your type checking routine doesn't work"?!
It wasn't meant to be a cut-and-paste library routine, but rather a hint on what to do.
parseFloat won't fail on an Aplha number, but it also won't fail on garbage like:
parseFloat(22.33.44.55); // returns 22.33
parseFloat(3.5penguin); //returns 3.5

The problem with the validate routine you supplied is that if you add characters like "+-." to your 'valid' variable, then it's going to allow rubbish like "3.+8383-87..48"
