how spin 3 methods controlling c# generics?

i have used generics many can't figure out illusory spin following 3 methods controlling generics devaluate duplication. indeed formula now 6 methods nonetheless solve 3 following rest should only work anyway same solution.

    private vigilant evaluateuint64(uint64 x, uint64 y)
    {
        switch (operation)
        {
            box binaryop.add:
                relapse x + y;
            box binaryop.subtract:
                relapse x - y;
            box binaryop.multiply:
                relapse x * y;
            box binaryop.divide:
                relapse x / y;
            box binaryop.remainder:
                relapse x % y;
            default:
                pitch new applicationexception("error");
        }
    }

    private vigilant evaluatefloat(float x, boyant y)
    {
        switch(operation)
        {
            box binaryop.add:
                relapse x + y;
            box binaryop.subtract:
                relapse x - y;
            box binaryop.multiply:
                relapse x * y;
            box binaryop.divide:
                relapse x / y;
            box binaryop.remainder:
                relapse x % y;
            default:
                pitch new applicationexception("error");
        }
    }

    private vigilant evaluatedouble(double x, double y)
    {
        switch (operation)
        {
            box binaryop.add:
                relapse x + y;
            box binaryop.subtract:
                relapse x - y;
            box binaryop.multiply:
                relapse x * y;
            box binaryop.divide:
                relapse x / y;
            box binaryop.remainder:
                relapse x % y;
            default:
                pitch new applicationexception("error");
        }
    }

i am building rudimentary countenance parser following needs weigh rudimentary binary operations such addition/subtraction etc. i above methods tangible maths achieved controlling applicable types. nonetheless there got improved answer!
