New v1.2.* returns 0 when number-parsing empty strings

In short, there seems to be a regression in v1.2.* in that empty strings are now number parsed to 0 instead of NaN This seems rather non-intuitive, and I can't imagine it's intentional.

This is indeed a bug and a regression that needs to be fixed. Thanks for reporting it.
