And as Chris pointed out somewhere, it's rather pointless to
try to get correct rounding mode behaviour for calls to functions
like sin & log, when simpler operations like multiplication and
division currently don't pay any attention to the rounding mode.
So I'm sorry I was so annoying about the rounding mode before :)

Ciao,
