问题描述
decimal d1 = 4.0m;
decimal d2 = 40.0m;
decimal d = d1 / d2;
string repr = d.ToString();
在Windows中，我得到0.1的再版。在Mono（Xamarin的Android），我得到0.1000000000000000000000000000左右。是什么赋予了？另外，我见过的建议通过1.0000000000000000000000000000米分来摆脱不必要的尾随零的。这并不对Xamarin的Android无论是工作
On Windows, I get "0.1" for repr. On Mono (Xamarin Android), I get "0.1000000000000000000000000000" or so. What gives? Also, I've seen recommendations to divide by 1.0000000000000000000000000000m to get rid of unwanted trailing zeroes. That doesn't work either on Xamarin Android.
已知的bug？上或技术上不是一个错误 - 这是允许符合标准的一致性
Known bug? Or technically not a bug - is this allowed in conformance with the standard?
要摆脱零，我的价值转换为字符串，删除尾随零呢？从字符串，并将其转换回为十进制。这是非常弱的。另外，我的解决方案不会产生我想确切的结果。我宁愿离开后是适当显著，而不是删除所有尾随零零。
To get rid of the zeroes, I'm converting the value to a string, removing trailing zeroes from the string, and converting it back to a decimal. It's pretty weak. Also, my solution doesn't produce the exact results I'd want. I'd prefer to leave trailing zeroes that are appropriately significant, rather than removing all trailing zeroes.
推荐答案
也许这是值得注，这个错误已得到修复，由米格尔奥德伊卡萨说：
Maybe it's worth a note, that this bug has been fixed, as stated by Miguel de Icaza: https://bugzilla.novell.com/show_bug.cgi?id=655780#c2
