Think that was it, using volatile variables makes a difference.  
( I hate! cheating compilers and I hate me again and again seeking for that
same trap ... sorry )   

reg. 'availability': think that 'modul' / each 'modul' which provides the
datatype should also provide the rounding mode ... good logic? Effort to
implement is once, users seeking would be over and over again ... endless ...
not good.
