类型: double 最大值: DBL_MAX 的值通常大约为 (1.7976931348623157 \times 10^{308})。 2. FLT_MAX 类型: float 最大值: FLT_MAX 的值通常大约为 (3.402823466 \times 10^{38})。 使用示例 以下是一个简单的 C++ 示例,展示了如何使用 FLT_MAX 和 DBL_MAX: cpp #include <iostream> #include <cflo...

最终,我发现了这个问题,但对我来说,这种行为仍然很奇怪:直接向int转换的int似乎被限制在MAX_INT上,用于有符号整数,而double强制转<em 浏览2提问于2012-05-17得票数 8 回答已采纳 1回答 C++双大小/溢出问题 、、 最近我遇到了一些奇怪的事情,我很难理解。double test = 1.8*pow(10,308);test = 1.7*po...
函数集提供了精度的控制。可以按照要求输出小数点后固定格式的字符串。比如:125.000 (精确到小数点后3位)。 #include<boost/lexical_cast.hpp> #include<cmath> #include<iomanip> usingboost::lexical_cast; boolDouble2MFCStr(doubledValue, CString&str,intprecision) ...
