It just uses the machine floating point implementation, which is most
oftenly IEEE. However the good news are - if someone manually writes
functions for IEEE number representation, they could be used exactly the
same way as Float and Double, and chances are good that with some
optimizer RULES the operations can be replaced by efficient FPU operations
on IEEE compliant FPUs.
