NAME

trapov − trap and repair floating point overflow

SYNOPSIS

subroutine trapov (numesg, rtnval)
double precision rtnval

DESCRIPTION

NOTE: This routine applies only to the Vax. It is ignored on the pdp11.

This call sets up the signal handler to trap and repair floating point overflow.  The first numesg occurrences of an overflow error will cause the message “Overflow!” to appear on the standard error file.  The value given for rtnval will replace the value generated by the overflow.  This must be a double precision value. For example, “0d0” or “dflmax()”.
