asinh() function in C++ STL
C++ STL Function : asinh()
The asinh() function uses a mathematical formula to calculate the inverse hyperbolic sine of a number. This formula involves the use of exponential functions and involves the ratio of the sides of a right triangle in a hyperbolic coordinate system.In this section, we will discuss about library function asinh() in STL which is used in C++.The Standard Template Library(STL) is a set of complete data structures and functions which can be used in C++.
Library Function asinh() in C++
In C++ programming language, the asinh function is included in standard template library.
The range of input argument which is passed to floor function is not limited here as it can be any value such as float or long double also.
Declaration of asinh function
asinh(data_type x)
Parameters of asinh function
The asinh function accepts a single input argument which is the hyperbolic angle and can be a double/float or long double value.
| Parameter | Description |
|---|---|
| Hyperbolic angle | This value of the parameter can be of double / float /int or long double type. |
Return value of asinh function
The asinh function returns the inverse hyperbolic sine value of the argument passed.
| Parameter | Return Value |
|---|---|
| Inverse hyperbolic sine of the argument passed | It returns the value in double / float / int or long double type. |
Implementation of STL Function asinh() in C++
Example 1:
The following code shows the use of asinh function.
#include<bits/stdc++.h>
using namespace std;
int main()
{
int x = -50.0;
double result = asinh(x);
cout << "asinh(-50.0) = " << result << " radians"<< endl;
cout << "asinh(-50.0) = " << result * 180 / 3.141592<< " degrees" << endl;
return 0;
}
Output:
asinh(-50.0) = -4.60527 radians asinh(-50.0) = -263.863 degrees
Example 2:
#include<bits/stdc++.h>
using namespace std;
int main()
{
string x = "mno";
double result = asinh(x);
cout << "asinh(50.0) = " << result << " radians"<< endl;
cout << "asinh(50.0) = " << result * 180 / 3.141592<< " degrees" << endl;
return 0;
}
Output:
prog.cpp: In function ‘int main()’:
prog.cpp:12:28: error: no matching function for call to ‘asinh(std::__cxx11::string&)’
double result = asinh(x);
