     cd2 = cos(cd1)

     cd4 = cqcos(cd3)
     cd4 = cos(cd3)

     r4 = cosd(r3)

DESCRIPTION
     cos returns the real cosine of its real argument.  dcos returns the
     double-precision cosine of its double-precision argument.  qcos returns
     the real*16 cosine of its real*16 argument.  ccos returns the complex
     cosine of its complex argument.  zcos returns the complex*16 cosine of
     its complex*16 argument.  cqcos returns the complex*32 cosine of its
     complex*32 argument.  The argument for these functions must be in radians
     and is treated modulo 2*Pi.

     The generic cos function becomes dcos, qcos, ccos, zcos, or cqcos as
     required by argument type.
     cosd returns the real*4 cosine of its real*4 argument.  dcosd returns the
     real*8 cosine of its real*8 argument, and qcosd returns the real*16
     cosine of its real*16 argument.  The argument for cosd, dcosd, and qcosd
     must be in degrees and is treated as modulo 360.

     The generic cosd function becomes dcosd or qcosd as required by argument
     type.
