- CCOOTT is the generic function name; the others are specifics. They are
- elemental intrinsic functions. They accept the following argument:
-
- _x Must be of type real. The type and kind type of _x is
- identical to the type and kind type of the return value.
- See the RETURN VALUES section for more information on input
- data types and return values.
-
- These functions evaluate _y = cot(_x).
-

- The CCOOTT and DDCCOOTT intrinsic function names can be passed as arguments;
- the others cannot.
-
- On UNICOS and UNICOS/mk systems, the following return values occur:
-
- * On systems that support the IEEE standard for floating-point
- arithmetic, 25
- CCOOTT((_x)) = NaN if |_x| > pi * 2 or if _x = NaN
-
- * On systems that do not support the IEEE standard for floating-point
- arithmetic, 25
- CCOOTT((_x)) = 0 if |_x| > pi * 2 or if _x = 0
-
- On IRIX systems, the following return value occurs:
-
- 19
- CCOOTT((_x)) = NaN if |_x| > pi * 2 or if _x = NaN

- CCOOTT and CCOOTTAANN return the single-precision real cotangent of their
- single-precision real arguments.
-
- DDCCOOTT and DDCCOOTTAANN return the double-precision real cotangent of their
- double-precision real arguments.
-
- QQCCOOTT and QQCCOOTTAANN return the quad-precision real cotangent of their
- quad-precision real arguments.
-
- The data type and kind type for single-precision, double-precision,
- and quad-precision values differ depending on your platform. For
- platform-specific information, see the TERMINOLOGY section of the
- IINNTTRROO__IINNTTRRIINN(3I) man page.
