TDI used some routines for single precision floats that were originally
written in about 1982. The routines for the doubles were taken from some code
for the MAC. Just thought I'd mention those things. I don't know if there is
any real advantage to using IMPORTed math routines like that or not. I do
understand that IEEE maintains a greater level of accuracy. I'd think it best
to be able to option which (FFP or IEEE) one to use.
