Truncate Two decimal places without rounding

Question

Lets say I have a value of 3.4679 and want 3.46, how can I truncate to two decimal places that without rounding up?

I have tried the following but all three give me 3.47:

void Main()
{
    Console.Write(Math.Round(3.4679, 2,MidpointRounding.ToEven));
    Console.Write(Math.Round(3.4679, 2,MidpointRounding.AwayFromZero));
    Console.Write(Math.Round(3.4679, 2));
}

This returns 3.46, but just seems dirty some how:

void Main()
{
    Console.Write(Math.Round(3.46799999999 -.005 , 2));
}

Answer 1

value = Math.Truncate(100 * value) / 100;

Beware that fractions like these cannot be accurately represented in floating point.

Answer 2

would this work for you?

Console.Write(((int)(3.4679999999*100))/100.0);

Answer 3

Would ((long)(3.4679 * 100)) / 100.0 give what you want?

Answer 4

((long)(3.4679 * 100)) / 100.0 - This is GREAT!! it works for me! i've been looking for a way to do this and it finally works!!! thanks a bunch!!
