[英]How can I format a number but show all digits of precision?
When a user goes to edit a number, I want to format a number to have a thousands separator in one case (and a percentage sign in another) but I want to be able to show absolutely all available digits of precision. 当用户去编辑数字时,我想格式化数字以在一种情况下具有千位分隔符(在另一种情况下具有百分号),但是我希望能够显示绝对所有可用的精度数字。
When the number is being displayed, its format is simply {0:0,0;-0,0; - }
显示数字时,其格式仅为
{0:0,0;-0,0; - }
{0:0,0;-0,0; - }
, (or {0:0,0.00;-0,0.00; - }
to show two decimal places), but when my control goes into edit mode, I want to switch to displaying something very similar, but showing all available digits of precision. {0:0,0;-0,0; - }
(或{0:0,0.00;-0,0.00; - }
以显示两位小数),但是当我的控件进入编辑模式时,我想切换为显示非常相似的内容,但显示所有可用数字的精度。 Is there any way to do this short of creating a format string that looks like this? 除了创建像这样的格式字符串外,还有什么方法可以做到这一点?
{0:0,0.#############################;-0,0.###...
I want to do something similar with percentages. 我想对百分比做类似的事情。 I want to displayed value to be
{0:0.00 %;-0.00 %; - }
我想将值显示为
{0:0.00 %;-0.00 %; - }
{0:0.00 %;-0.00 %; - }
until the user activates the cell for editing, at which time the format should still be a percentage, but showing more digits of precision if they exist in the underlying value. {0:0.00 %;-0.00 %; - }
直到用户激活单元格进行编辑为止,此时格式仍应为百分比,但是如果基础值中存在精度数字,则显示更多精度。
Thanks 谢谢
This question is similar to yours. 这个问题和你的相似。 (The answer is that it's not possible with the .NET built-in custom numeric formatting.)
(答案是,.NET内置自定义数字格式不可能。)
