floating-point exceptions

[John D. McCalpin]

How does one modify the response of the floating-point exception
handler on the IRIS 4D machines?  What I want to do is to turn off
error handling for operations which have NaN as an operand, so that
the code will simply continue.

I know that in this case, the effects of the NaN's will be limited,
since the problem occurs in the scaling of some results for output....

Thanks....
