cos(3F)                                                   cos(3F)



NAME
     cos, dcos, ccos, zcos, cdcos - Fortran cosine intrinsic
     function

SYNOPSIS
     real r1, r2
     double precision dp1, dp2
     complex cx1, cx2
     double complex dx1, dx2

     r2 = cos(r1)

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

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

     dx2 = cdcos(dx1)
     dx2 = zcos(dx1)
     dx2 = cos(dx1)

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.  zcos and cdcos return the double-precision com-
     plex cosine of their double-precision complex argument.  The
     generic form cos may be used with impunity as its returned
     type is determined by that of its argument.
