浮点显示最多2个数字 [英] Float point display upto 2 number

问题描述

你好朋友，


我有一个问题，当我得到像0.67543这样的结果时，我只希望像0.67这样的结果.表示(.)点后仅显示2个数字

这是我的代码

Hello Friends,


I have problem that when i get the result like 0.67543 i want that result like 0.67 only. means there is only 2 number show after (.) dot

here is my code

float calc = 0;
float lenght=0, breadth=0, height=0;
lenght = float.Parse(txtlenght.Text);
breadth = float.Parse(txtbreath.Text);
height = float.Parse(txtheight.Text);
calc = ((lenght * breadth * height) / 6000);

calc = Convert.ToInt32((float)Math.Round(calc, 3));

if (calc != 0)
{
    lblresult.Text = "Your Volumetric Weight is :  " + calc.ToString() + "Kg.";
}

推荐答案

尝试:

lblresult.Text = "Your Volumetric Weight is :  " + calc.ToString("0.00") + "Kg.";

lblresult.Text ="您的体积重量为:"+ calc.ToString(" ###，###.000)+" Kg.;

lblresult.Text = "Your Volumetric Weight is : " + calc.ToString("###,###.000")+ "Kg.";
