By design, why does the C# compiler allows any float or double values to be divided by zero?

class Program
{
    static void Main(string[] args)
    {
        double x = 0.0 / 0;

        float y = 1f / 0;


    }
}

    Because IEEE 754 floating-point values have special non-numeric values to deal with this:

    PS Home:\> 1.0/0
Infinity
PS Home:\> 0.0/0
NaN

    whereas dividing an integer by zero is always an exception (in the C# sense1), so you could just throw the exception directly.

    1 Dividing a floating-point number by zero is also an exception but at a completely different level and many programming languages abstract this away.
