COS(3F)                              SysV                              COS(3F)



NAME
     cos, dcos, ccos - FORTRAN cosine intrinsic function

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

     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 as its returned type is determined by that of its
     argument.
