cos(3F)                                                   cos(3F)



     NAME
          cos, dcos, ccos - FORTRAN cosine intrinsic function

     SYNOPSIS
          real r1, r2
          double precision dp1, dp2

          r2 = cos(r1)

          dp2 = dcos(dp1)
          dp2 = cos(dp1)

          cx2 = ccos(cx1)
          cx2 = cos(cx1)

     DESCRIPTION
          cos returns the real cosine of its real argument.  dcos
          returns the double-precision cosine of its double-precision
          argument.  ccos returns the complex cosine of its complex
          argument.  The generic form cos may be used with impunity
          because its returned type is determined by that of its
          argument.
