parseInt VS parseFloat (v2)

Revision 2 of this benchmark created by Brian Blakely on

Description

Exactly what the name says. Finally, the gloves are off.

VERDICT!

Chrome likes parseFloat more, unless you're trying to actually grab the integer value out of a floating-point string.

Firefox is just the opposite! What a country!
