#32943 [Bgs]: is_numeric validates "3e0"

ID: 32943 User updated by: pmorgan at ukds dot net Reported By: pmorgan at ukds dot net Status: Bogus Bug Type: Scripting Engine problem Operating System: Linux PHP Version: 4.3.10 New Comment: That needs to go into the manual "number in e-notation", which I understand, or even better as an additional flag "allow_e-notation". It's the last error I would have expected and is very misleading AFAIK.
