--- Comment #2 from Stefan Brüns <stefan.bruens@rwth-aachen.de> ---
I agree the numerical error introduced by truncating/casting is somewhat
expected.

The strange part is for ~every other architecture, 1.034567 apparently gets
rounded up for some immediate value/type (double?), while for ix86 it gets
rounded down.
