Given the poor FP on RISC OS, developers go out of their way not to 
use it, using fixed point if at all possible. On other platforms with 
highly accelerated FP, there isn't the stigma, so it's used for many 
things such as 3D graphic APIs, codecs, and lots of other things - all 
of which have been ported to RISC OS at one time or another and found 
to be hideously slow.
