Dear Lars,

thanks for the notifiation

this bug is still around https://trac.mathweb.org/OM3/ticket/114, it is 
scheduled for this round. There is another, related one 
https://trac.mathweb.org/OM3/ticket/107. Maybe you can have a look over 
these?
> 2. The standard only covers 64-bit (I think it was) IEEE floats, but the
> current IEEE 754 standard defines 32n-bit floats for all integers n>=4. (Cf.

Maybe you can make a bug out of this and schedule it for OM2+OMOBJ?
