There is an issue with the function predictates isInteger() and isFloat() where a number is passed in an array of length 1.

eg:

_.isInteger([1])
// true
_.isFloat([1.1])
// true
// both should be false.

The fix for this should be pretty easy by just adding if (i === undefined || i === null || i instanceof Array) return false to the top of isNumeric.

This simple gate will block undefined, null and array.

Suggestions?
