https://community.intel.com/t5/Software-Archive/fpe-0/m-p/957688#M21173 If I have some code like this (and compile with fpe:0) on a Pentium 4: <BR /> <BR /> REAL*8 X,BETA <BR /> REAL*4 RCINPUT <BR /> <BR /> ! WHEN X IS 48.0 <BR /> ! BETA IS 5.0 <BR /> <BR /> FFALLE = EXP(-X*X/BETA/BETA) <BR /> <BR /> ! FFALLE BECOMES 9.45E-41 <BR /> <BR /> RCINPUT = FFALLE <BR /> <BR />I would expect the the real*4 RCINPUT would be set to 0.0. Or am I misunderstanding /fpe:0. RCINPUT does not get set to 0.0 in the debugger.
