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));
}

Note: Floating-point operation return PositiveInfinity to indicate an overflow condition.
