Question

I have below digits. I want to show one digit after to decimal. How to format it?

2.85
2
1.99

I was using (“{0:0.0}”. But data showing like

2.9 //It should be 2.8
2.0 //It should be 2
2.0 //It should be 1.9

Answer 1

Try using "{0:0.#}" as the format string. However, that will only fix the .0. To fix the rounding to always round down, you might want to use:

string s = (Math.Floor(value * 10) / 10).ToString("0.#");
