Purpose
Hyperbolic cosine function.
Class
Elemental function
Argument type and attributes
- X
- An INTENT(IN) REAL
or COMPLEX.
Result type and attributes
Same as X.
Result value
The result value approximates cosh(X).
If X is of type complex, its imaginary part
is considered a value in radians.
Examples
COSH(1.0) has the value 1.5430806, approximately.
COSH((1.000000,
0.000000)) has the value (1.543081, 0.000000), approximately.

|---|---|---|---|
| COSH | default real | default real | yes |
| DCOSH | double precision real | double precision real | yes |
| QCOSH 1 | REAL(16) | REAL(16) | yes |
