Hello 
May I miss something on VCLUIPack, I didn't see any numeric edit with exponent capabilities.
For exemple typing 1,25E-3, with an autoevaluate function (autoevaluate true/false)
showing immediatly 0,00125 (or not if false) with actual precision in Advedit, keeping the value entered.
Best regards
At this moment, we do not have this functionality.
Closest we have is AdvEdit with edit style etValidChars where you allow to enter number + E + sign.
But it won't validate nor auto evaluate.
We'll consider this for a future version.
It would be great. As usal, I'm sure you and your team will rocks again :)
