- CCOOTT is the generic function name. CCOOTT and DDCCOOTT are elemental
- functions for the CF90 compiler.
-
- These functions evaluate _y = cot(_x).

- DDCCOOTT is an outmoded routine for the CF90 compiler. Refer to the
- _F_o_r_t_r_a_n _L_a_n_g_u_a_g_e _R_e_f_e_r_e_n_c_e _M_a_n_u_a_l, _V_o_l_u_m_e _3, publication SR-3905, for
- information about outmoded features and their preferred standard
- alternatives.
-
- The name of this intrinsic can be passed as an argument.
-
- RREETTUURRNN VVAALLUUEESS
- CCOOTT returns the real cotangent of its real argument.
-
- DDCCOOTT returns the double-precision cotangent of its double-precision
- argument.
-
- On CRAY T90 systems that support IEEE arithmetic, the following return
- values occur:
- 25
- CCOOTT((_x)) = NaN if |_x| > 2 * pi or _x = NaN
