Hi all,

What do I learn from this?
(a) Fractional point font sizes are not a thing, and I shouldn't do that?
(b) Fractional point font sizes may work, but are unreliable?
(c) \switchtobodyfont[script] doesn't work with fractional point font sizes?
(d) Something else entirely?
Hi Jim,
just use the source: lines 654-662 from contain the explanation (or I
just found the fix reading those lines).
If you use non-predefined font sizes (not just fractional, `50pt` gives
the same result), it seems that you have to setup the size.
Your sample compiles fine, even with such an unorthodox approach such as:
\definebodyfontenvironment[10.5pt]
[script=\cldcontext{10.5*(7/12)}pt]
\setupbodyfont[10.5pt]
I hope it helps,
In mkii times there we limnitation son the amount of fonts so we snapped
sizes to 2 digits. In mkiv times that was less needed but still we snap
in order not to get excessive definitions due to 'interesting usa
cases'. In lmtx we scale differently but still one needs to be careful
esp as bodyfont environments are expected to behave consistently.
In principle we could discard some compatibility here but that is always
tricky and as such some work from Wolfgang and me that we currently
happily delay. Of course there are sentimental reasons for such a delay
too.
