McCalpin) Newsgroups: comp.sys.sgi Subject: floating-point exceptions Message-ID: Date: 24 Nov 89 17:59:42 GMT Sender: news@stat.fsu.edu Distribution: usa Organization: Supercomputer Computations Research Institute Lines: 13 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.... -- John D.
