https://community.intel.com/t5/Software-Archive/Ignoring-Alpha-OpenVMS-arithmetic-error/m-p/972707#M24344 I suspect that on the other systems, you get an IEEE NaN, not a zero. You can get that too on VMS, but need to compile with /FLOAT_TYPE=IEEE /IEEE_MODE=UNDERFLOW_TO_ZERO There is no environment setting that will do this for you, as it requires completely different generated code.<BR /><BR />Steve Thu, 08 Nov 2001 06:19:06 GMT Steven_L_Intel1 2001-11-08T06:19:06Z https://community.intel.com/t5/Software-Archive/Ignoring-Alpha-OpenVMS-arithmetic-error/m-p/972706#M24343 Is there any way on such a system to ignore certain arithmetic errors through environment settings rather than by compilation options? <BR /> <BR />I am getting a high performance arithmetic error for what it detects as a divide by zero. (I know, sloppy code). The same code on Windows or various Unix systems works -- it apparently returns a zero, which is OK. <BR /> <BR />The issue is that this was compiled on a customer system on the other side of the world and we do not have an Alpha system or essentially any OpenVMS knowledge. <BR /> <BR />Thanks for any help.
