问题描述

当我尝试"计算涉及除法的表达式时，我没有得到正确的答案.例如:双数= 5/9； Console.WriteLine(number.ToString());，结果为0！这里发生了什么?为什么我没有得到.55555 ...?

When I "attempt" to calculate a expression that involves division I''m not getting the correct answer. Example: double number = 5/9; Console.WriteLine(number.ToString());, the result is 0! What''s going on here? Why am I not getting .55555...?

推荐答案

您需要做的是:

what you would need to do is:

double number1 = 5.0/9.0;
double number2 = (double)5/(double)9;
double number3 = 5D/9D;

谢谢.那行得通，但考虑到我最初声明数字"为双精度，为什么我不知道为什么必须强制转换为双精度?您能跟我澄清一下吗?

thanks. that worked but I don''t understand why I had to type cast to double considering that I initially declared "number" a double? would you please clarify this with me?

谢谢！我即将检查您发送给我的MSDN链接.再次感谢您！

thank you! I''m about to check out the MSDN link you sent me. Again thank you!
