Oh, neat!

You mean we have to choose between hardware floating point
calculations or doing this in software? If it is possible, it would
be nice to do this in hardware, also because this will reduce the code
size.
But floating point instructions are not used that much so I will apply
this patch.
Thanks,
Marco
