Looking at the title, I couldn't figure out what mw55309 was asking.

All I could think of was "vbles vobble but they don't fall down" :)

By the way, "0.234+E06" isn't a valid number, or at least, it isn't 234000.

perl won't complain, but it evaluates to 0.234. You probably meant "0.234E+06".

Abigail-II is right, as usual; the regexen in the FAQ answer would catch that error.
