complex cx1, cx2
complex*16 cd1, cd2
complex*32 cd3, cd4
real*4 r3, r4

r2 = cos(r1)
dp2 = dcos(dp1)
dp2 = cos(dp1)
qp2 = qcos(qp1)
qp2 = cos(qp1)
cx2 = ccos(cx1)
cx2 = cos(cx1)
cd2 = zcos(cd1)
cd2 = cos(cd1)
cd4 = cqcos(cd3)
cd4 = cos(cd3)
r4 = cosd(r3)
dp4 = dcosd(dp3)
dp4 = cosd(dp3)
qp4 = qcosd(qp3)
qp4 = cosd(qp3)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.
