C++ cmath cosh() function
Example
Return the hyperbolic cosine of different numbers:
cout << cosh(7);
cout << cosh(56);
cout << cosh(2.45);
Definition and Usage
The cosh() function returns the hyperbolic cosine of a number.
The hyperbolic cosine is equivalent to (exp(number) + exp(-number)) / 2.
The cosh() function is defined in the <cmath> header file.
Syntax
One of the following:
cosh(double number);cosh(float number);Parameter Values
| Parameter | Description |
|---|---|
| number | Required. Specifies a number. If the number is an integer type then it will be treated as a double. |
Technical Details
| Returns: | A float value (if the argument is float) or double value (in any other case) representing the hyperbolic cosine of a number. |
