将小数值转换为指数格式?

问题描述

嗨
我的Form1中有一个文本框

我想将文本框值转换为指数格式
例如:指数取0.0009.

在鼠标离开时

Hi
I have a Textbox in my Form1

I Want to convert Textbox value into Exponent Format
Exa: 0.0009 into Exponent.

In Mouse Leave

double d;
d = Convert.ToDouble(T1.Text);
T1.Text = d.ToString("E");

在鼠标上方

In Mouse over

double p = double.Parse(T1.Text, System.Globalization.NumberStyles.Any);
T1.Text = p.ToString();

我得到的0.0009结果是9.000000E-004
但我希望输出为9E-004.
如何从指数值中避免零?

让我知道你是否有任何想法.

谢谢&问候
