Yeah, well... It's actually the perl regular expression matcher of PHP ... So I guess there might be some caveats that I'm not aware of . lieven sterck wrote:
with me they both work :-/ but... ALWAYS be careful when using the ' | ': actually it says in your regex: \d+ or 0 it does NOT refer to the previous chars only the one just in front of the pipe. if you group them with () then it says what you want to it to say.

(\d*(e-|\.)\d+)
Okay,
I need a small regexp to recognize e-values . I thought this one would suffice: (\d*e-\d+|0\.\d+)
But apparently it only recognizes:
e-126 2e-20 1e-09 0.001 0.004 0.015
And not: 0.23 0.90
Can anyone tell me why this is the case? I'm slightly confused :/
