Oops.
I will discuss with Marty how we should tackle this and what the "proper"
behaviour of a record should be, but I definitely think that we need to
review and fix the standard record types before the next release of Base.
Thanks for the problem analysis, which Jeff has filed in Mantis as bug #144.
How do you catch NaN? Different from most C/C++ compilers
and standard C/C++ libraries,
the one we use for vxWorks/Tornado 2.0.2 does not define "isnan()".

On R3.14.x epicsMath.h is an OS-specific header that ensures isnan() and
isinf() are defined on all supported platforms, so detecting NaNs should
be portable provided you include that header.
