FPE (II) 9/2/72 FPE (II) NAME fpe -- set floating exception handling SYNOPSIS sys fpe; arg / fpe = 40. not in assembler DESCRIPTION This call allows one to catch traps resulting from floating point exceptions. Arg is a loca- tion within the program; floating exception traps are sent to that location. The normal effect of floating exception traps may be restored by giv- ing an arg equal to 0. To return after catching the fpe trap, execute the rti instruction. SEE ALSO -- DIAGNOSTICS -- BUGS The floating point exception (FEC) register is not saved per process. Examining this register for possible remedial action after a floating point exception trap is not guaranteed to work.
