没有为复杂类型定义关系运算符(没有“小于”的概念)在复杂类型和其他算术类型之间定义隐式转换。 为了支持复数运算的单一无穷大模型,C 将具有至少一个无限部分的任何复数值视为无穷大,即使其另一部分是 NaN,也保证所有运算符和函数都遵守入口的基本属性并提供cproj将所有无穷大映射到规范的一个(请参阅算术运算符以...

gcc 4.9.1编译运行(未加任何特殊编译选项)的结果是打印第二条. 而vs2013默认编译不通过, error:负数转变成了无符号数. 开始看 <<Expert C programming -- Deep C Secrets>>这本书这里时有点偷懒, 只记得了这两句话: Operands with different types get converted when you do arithmetic. Everything is conv...

1 2 (0 – 1) ==uint.MaxValue;// uint.MinValue = 0 (uint.MaxValue + 1) == 0; This also applies to conversions too: 1 (int)((long)int.MaxValue + 1) ==int.MinValue;// true Pitfalls This default behaviour of swallowing the exceptions seems rather strange and unexpected to me,...
Recently, the good folks in the Windows division set out to create small set of C functions (obviously, you can use them in C++ code too) to perform safe integer arithmetic. These functions are used mainly to perform safe memory allocation calculations and array offset calculations. The small...
Arithmetic is a fundamental branch of mathematics that focuses on the study of numbers, calculations, and mathematical operations. It deals with the basic mathematical operations of addition, subtraction, multiplication, and division, as well as more advanced concepts such as fractions, decimals, and...
