# [NTG-context] Second derivative ''

Dear List,

\starttext
\startformula
\left(f\right)'' = f''
\stopformula
\stoptext

has the second apostrophe set too low. This is in MKIV on ConTeXt live as well
as in my slightly older version.
What is the “right” way to typeset a second derivative?

Thanks,

Matthias
