Single.IsNaN() Method in C# with Examples
In C#, Single.IsNaN(Single) is a Single struct method. This method is used to check whether the specified floating-point value is not a number (NaN).
Syntax: public static bool IsNaN (float f);
Parameter:
f: It is a single-precision floating-point number of type System.Single.
Return Type: This function returns a boolean value i.e. True, if specified value is not a number(NaN), otherwise returns False.
Example:
// C# program to demonstrate // Single.IsNaN(Single) method using System; class GFG { // Main Method public static void Main(String[] args) { // first example float f1 = 1.0f / 0.0f; bool res = Single.IsNaN(f1); // printing the output if (res) Console.WriteLine(f1 + " is NaN" ); else Console.WriteLine(f1 + " is not NaN" ); // second example // it will give result // NaN float f2 = 0.0f / 0.0f; bool res1 = Single.IsNaN(f2); // printing the output if (res1) Console.WriteLine(f2 + " is NaN" ); else Console.WriteLine(f2 + " is not NaN" ); } } |
Output:
Infinity is not NaN NaN is NaN
Note:
- This method returns false if a Single value is either PositiveInfinity or NegativeInfinity.
- Floating point operation returns a NaN to show that the result of the operation is undefined.
