Express mathematical infinity in C#

Question

Is it possible to express (mathematical) infinity, positive or negative, in C#? If so, how?

Answer 1

public const double NegativeInfinity = -1.0 / 0.0;
public const double PositiveInfinity = 1.0 / 0.0;

Answer 2

double.PositiveInfinity

double.NegativeInfinity

float zero = 0;

float positive = 1 / zero;
Console.WriteLine(positive);    // Outputs "Infinity"

float negative = -1 / zero;
Console.WriteLine(negative);    // Outputs "-Infinity"

Answer 3

Yes, check constants values of types float and double, like:
float.PositiveInfinity
float.NegativeInfinity
Those values are compliant with IEEE-754, so you might want to check out how this works exactly, so you will be aware, when and how you can get those values while making calculations. More info here.

Answer 4

Use the PositiveInfinity and NegativeInfinity constants:

double positive = double.PositiveInfinity;
double negative = double.NegativeInfinity;
