[Qt-interest] Why this double is not valid by QDoubleValidator

[Scott Aron Bloom]

Are you not using this in a GUI?  Are you using it to parse bulk data?

 

If so.. look inside the QDoubleValidator code, find the regex they are
using and extend it to support an optional number at the end, rather
than a required number.

 

Or you might want to google "regex for doubles"

So can u  suggest how would I handle these data I have a large set of
data where may be the integer after E is missing it should be assumed to
be 0 if value is there.

Any idea !!

It's only scientific notation when there is an integer after the E.
Otherwise it isn't scientific notation, or in Qt's validator system,
