C++ Math isnormal() Function

C++ Math isnormal()

The function determines that whether the given number is normal or not. If the number is normal, it returns 1 otherwise 0.

Suppose a number is ‘x’. Syntax would be:

  bool  isnormal(float x);  bool  isnormal(double x);  bool  isnormal(long double x);  bool  isnormal(integral x);  

x: It is a floating point value.

Let’s see the simple example.

  #include   #include  using namespace std;  int main()  {     std::cout << “isnormal(5) is : ” <(5)

Output:

isnormal(5) is : 1  isnormal(5.0/0.0) is : 0  isnormal(0.0/0.0) is : 0
