C++ cmath acosh() function
Example
Return the inverse hyperbolic cosine of different numbers:
cout << acosh(7);
cout << acosh(56);
cout << acosh(2.45);
Definition and Usage
The acosh() function returns the inverse hyperbolic cosine of a number.
The acosh() function is defined in the <cmath> header file.
Syntax
One of the following:
acosh(double number);acosh(float number);Parameter Values
| Parameter | Description |
|---|---|
| number |
Required. A number to find the inverse hyperbolic cosine of. If the value is less than 1, the function returns NaN (Not a Number). If the number is an integer type then it will be treated as a double.
