- CCOOSSHH is the generic function name; the others are specifics. CCOOSSHH,
- DDCCOOSSHH, and QQCCOOSSHH are elemental intrinsic functions. These are
- elemental 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.
- _x -_x
- These functions evaluate _y = cosh(_x) = (_e + _e ) / 2.

- The CCOOSSHH and DDCCOOSSHH intrinsic function names can be passed as
- arguments; the other cannot.
-
- On CRAY T90 systems that support IEEE arithmetic, the following return
- values occur:
-
- CCOOSSHH((_x)) = infinity if |_x| > 709.78
-
- CCOOSSHH((_x)) = NaN if _x = NaN

- CCOOSSHH returns the single-precision real hyperbolic cosine of its
- single-precision real argument.
-
- DDCCOOSSHH returns the double-precision real hyperbolic cosine of its
- double-precision real argument.
-
- QQCCOOSSHH returns the quad-precision real hyperbolic cosine of its
- quad-precision real argument.
