EQV (3sciport)

Computes logical equivalence

SYNOPSIS

  boolean = EQV( arg1, arg2 )

FUNCTION VALUE

  eqv             Boolean. (Integer, Logical, or Real.)
                  The bit-wise boolean .EQV. of two 64 bit data items.

ARGUMENTS

  arg1            Integer, Logical, or Real.
                  A 64 bit input argument.

  arg2            Integer, Logical, or Real.
                  A 64 bit input argument.

DESCRIPTION

  The external function EQV returns the bit-wise boolean .EQV. of the input
  arguments, arg1 and arg2.

NOTES

  Since EQV is not an ANSI Fortran 77 intrinsic function, it must be declared
  as an external function of type integer, logical or real. For example:

          EXTERNAL EQV
          INTEGER  EQV
          ...
          I = EQV( X,'F0F0F0F0F0F0F0F0'X,'C3C3C3C3C3C3C3C3'X )
                                          ! Same as I = 'CCCCCCCCCCCCCCCC'X
