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 complex 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.
