C asinh() Prototype
double asinh (double x);
Function asinh() takes a single argument as double and returns the value in radians.
And, the returned value of asinh() is of type double.
For better understanding of asinh():
[Mathematics] sinh-1x = asinh(x) [In C programming]
Two other functions asinhf() and asinhl() are also present to specifically work with float and long double respectively.
The asinh() function is defined in <math.h> header file.
C asinh() range
The range of argument for asinh() can be any value from negative to positive.
Example: C asinh() function
#include <stdio.h>
#include <math.h>
#define PI 3.141592654
int main()
{
float num = 8.0;
double result;
result = asinh(num);
printf("Inverse of sinh(%.2f) = %.2f in radians", num, result);
// Converting radians to degree
result=(result*180)/PI;
printf("\nInverse of sinh(%.2f) = %.2f in degrees", num, result);
return 0;
}
Output
Inverse of sinh(8.00)=2.78 in radians Inverse of sinh(8.00)=159.08 in degrees
