- The one exception to this rule is the case
when you multiply Infinity by 0; The value of the expression Infinity * 0 is 0, although
the value of NaN * 0 is NaN. - If you are familiar with C or C++, you know that you can’t use the remainder operator on
float or double values in these languages. However, C# relaxes this rule. The remainder operator
is valid with all numeric types, and the result is not necessarily an integer. For example, the result
of the expression 7.0 % 2.4 is 2.2. - You cannot use the checked and unchecked keywords to control floatingpoint
(noninteger) arithmetic. The checked and unchecked keywords apply only to integer
arithmetic using data types such as int and long. Floating-point arithmetic never throws
OverflowException—not even when you divide by 0.0. (The .NET Framework has a representation
for infinity.) - 本文转自 xkdcc 51CTO博客，原文链接：http://blog.51cto.com/brantc/383438，如需转载请自行联系原作者
