Double.IsPositiveInfinity() Method in C#
In C#, Double.IsPositiveInfinity() is a Double struct method. This method is used to check whether a specified 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 (double d);
d: It is a double-precision floating-point number of type System.Double.
Return Type: This function return a Boolean value True, if specified value evaluates to positive infinity, otherwise return False.
Input : d = 10 / 0.0 Output : True Input : d = 7.997e307 + 9.985e307; Output : True
Code: To demonstrate the Double.IsPositiveInfinity(Double) Method
- Floating-point operation return Infinity (Positive Infinity) or -Infinity (Negative Infinity) to indicate an overflow condition.
- The result of any floating point operation that exceeds Double.MaxValue (i.e 1.7976931348623157E+308 ) is considered as Positive Infinity.
