Consider a number

number = 2.*10^20

It is in the representation of ScientificForm.

I convert it to C-form:

numberc=CForm[number]

How to convert it back?

CForm is just a wrapper. So if you do numberc[[1]] you will get back the original number. I do not know if this is what you meant? – Nasser Jun 06 '23 at 14:56

With cf = number // CForm then the number is just the first part of the CForm, i.e., number === cf[[1]] – Bob Hanlon Jun 06 '23 at 14:57
Thanks, this helped! – John Taylor Jun 06 '23 at 14:59
