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.

Syntax

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);

Parameter

x: It is a floating point value.

Return value

Parameter(x) Return value
Infinite 0
Normal value 1
Subnormal value 0
Not a Number 0

Example 1

Let's see the simple example.

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

Output:

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