如何将此字符串8.12345678E-04解析为数字? [英] How to parse this string 8.12345678E-04 into a number?

问题描述

大家好，我正在使用vb2010.
尝试将此字符串8.29933968E-04解析为一个数字，以便可以在电子表格中进行绘制.


如果此数字类似于1283912839E-5(即整数"&(E-xxx)，但数字中没有小数点)，则可以使用

字符串x ="1283912839E-5"
十进制dec = Decimal.Parse(x，NumberStyles.AllowExponent)

但这对我的电话号码无效.
我该怎么用?

Thx

Hi folks, I''m using vb2010.
Trying to parse this string 8.29933968E-04 into a number so I can plot in on a spreadsheet.


if this number were like 1283912839E-5(that is, ''integer''&(E-xxx) , without the decimal point in the number ) , then I could''ve used

string x = "1283912839E-5"
decimal dec = Decimal.Parse( x, NumberStyles.AllowExponent )

but this does not work for my number.
What should I use?

Thx

推荐答案

尝试:

string s = " 8.29933968E-04";
decimal d = decimal.Parse(s, System.Globalization.NumberStyles.Float);

您的字符串"不是有效的指数.它缺少小数点.

Your "string" is not a valid exponent. It''s missing a decimal point.
