NAME fpe -- set floating exception handling
SYNOPSIS sys fpe; arg / fpe = 40. not in assembler
allows one to catch traps resulting from
floating point exceptions.
Arg
\b\b\b___ is a location within the program; floating exception traps
are sent to that location.
The normal effect of floating exception traps may be restored by giving
an arg
\b\b\b___ equal to 0.
To return after catching the
trap, execute the rti
\b\b\b___ instruction.
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.
