Single.IsPositiveInfinity() Method in C# with Examples
In C#, Single.IsPositiveInfinity(Single) is a Single struct method. This method is used to check whether a specified floating-point value evaluates to positive infinity or not. In some floating point operation, it is possible to obtain a result that is positive infinity. For Example: If any positive value is divided by zero, it results in positive infinity.
Syntax: public static bool IsPositiveInfinity (float f);
Parameter:
f: It is a single-precision floating-point number of type System.Single.
Return Type: This function return a Boolean value True, if specified value evaluates to positive infinity, otherwise return False.
Example: To demonstrate the Single.IsPositiveInfinity(Single) Method
// C# program to illustrate the // Single.IsPositiveInfinity(Single) // Method using System; class GFG { // Main method static public void Main() { // Dividing a Positive number by zero // results in positive infinity. // Dividing a number directly by 0 // produces an error // So 0 is stored in a variable first float zero = 0.0f; float value = 10.0f; float result = value / zero; // Printing result Console.WriteLine(result); // Check result using IsPositiveInfinity() Method Console.WriteLine(Single.IsPositiveInfinity(result)); // Floating point operation that exceeds // Single.MaxValue is Positive Infinity result = (1.402823E+38f + (( float )9.985e307)); // Printing result Console.WriteLine(result); // Check result using IsPositiveInfinity() Method Console.WriteLine(Single.IsPositiveInfinity(result)); } } |
Infinity True Infinity True
Note: Floating-point operation return PositiveInfinity to indicate an overflow condition.
