isNumeric return true on array with only one numeric value

[mengsoon]

isNumeric return true when the test value is an array with only one numeric value.

eg: $.isNumeric([1,2]) will return false, but $.isNumeric([1]) will return true instead of false.

Confirmed in Chrome 15 and Firefox 8.

This is because the isNumeric method is using parseFloat which is coercing the array into a number.

Can we just update the  isNumeric documentation to make it clear that what's being checked is the argument's String representation?

What is there to change? That behaviour is correct.  http://es5.github.com/#x15.1.2.3

@rwaldron can't we at least just add this to the other examples, to make it clear? $.isNumeric("[1]");   true
