TRAPOV(3F)              COMMAND REFERENCE              TRAPOV(3F)



NAME
     trapov - trap and repair floating point overflow

SYNOPSIS
     subroutine trapov (numesg, rtnval)
     double precision rtnval

DESCRIPTION
          NOTE:   This routine is outdated by trpfpe.  See
                  trpfpe(3f) for the newer error handler.

     This subroutine sets up signal handlers to trap arithmetic
     exceptions.  Trapping arithmetic exceptions allows the
     user's program to proceed from instances of floating point
     overflow or divide by zero.  The result of such operations
     will be replaced by rtnval.

     The first numesg occurrences of a floating point arithmetic
     error will cause a message to be written to the standard
     error file.  Rtnval must be a double precision value. For
     example, 0d0 or dflmax().

FILES
     /usr/lib/libF77.a
                    f77 intrinsic function (math) and startup
                    library.

CAVEATS
     Other arithmetic exceptions can be trapped but not repaired.
