Hyperbolic cosine function.
Elemental function
Same as X.
The result value approximates cosh(X).
If X is of type complex, its imaginary part is considered a value in radians.
COSH(1.0) has the value 1.5430806, approximately.
COSH((1.000000, 0.000000)) has the value (1.543081, 0.000000), approximately.
