COS(3F)                 COMMAND REFERENCE                 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.

SEE ALSO
     sin(3m).
