These rounding modes are controlled by bits in a control register.
Separating them from the format string allows one to test the stability of
the entire (or portions) of the math code. I have never seen anyone attempt
to plant this specification inside of a format string. If it matters for
printout, then surely it also matters elsewhere in the code.
