## What is tanh in c programming?

tanh in c is a mathematical function which is used to calculate hyperbolic tangent of a given number.

This function is defined in math.h header file.

### Prototype of tanh in c

`double tanh(double m);`

### Parameters

tanh function takes floating point value as input parameter.

### Return value

tanh function returns hyperbolic tangent value of a given number.

## Example program for tanh in c

```
#include<stdio.h>
#include<math.h>
int main()
{
double m=0.9,res;
res=tanh(m);
printf("Hyperbolic tangent value is %lf \n",res);
return 0;
}
```

While using gcc use below command to add math header.

`gcc file_name.c -lm`

### Code explanation

The hyperbolic tangent value of a given number is found by calling the tanh function. The result is being printed onto the console.
