[ECOS] floating point

[David N. Welton]

I am still running into problems with floating point.  It works fine
with the non-lazy switching, but gives me very funny results with it.
For instance, a variable that only has +=, -= and = applied to it
sometimes turns into a NaN.

As I'm interested in learning more about how things work, I would like
to try and track this down or at least figure out how...  I'm not sure
the best way of debugging problems at this level.  Any suggestions?

Another question - I'm I correct in assuming that the built in libm
functions are not overridden with hardware-supported functions (fsin
on x86, for instance)?
