Hello,


I can get out with \ifdim 12mu>3mu ?

Is this possible with TeX ?
eTeX \mutoglue ?

Thanks in advance.

No: the mu unit depends on the current math symbol font,
which in turn depends on the current math style, which can
be unknown at the moment. However, comparison between muglue
parameters can be done safely, I guess. Of course one doesn't
really asks for

\ifdim 12mu > 3mu

Did you try? :)

\ifdim\mutoglue\thickmuskip>\mutoglue\thinmuskip YES\else NO\fi

Don't compare muglues with normal or dimensions, since
\mutoglue just changes 1mu into 1pt, i.e., it doesn't
measure the muglue (by the above reason).
