boost::multiprecision::cpp_bin_float<200> Test1, Test2; Test1 = 1.0; Test2 = 2.0; Test1 = Test1 + Test2; 虽然前三行工作正常,但我在第四行中得到了一个错误:“找不到匹配的操作符”。另外,也没有找到.convert_to<double>(),我稍后将需要它。对cpp_dec_float来说也
这个答案是基于@Sehe所提供的。 它为Boost的mp::cpp_dec_float_50的序列化和反序列化提供了工具。 由于no_header标志不遵守,因此Boost的序列化接口(大约10字节前缀)在通过序列化接口进行交互时插入,而且由于不知道这些字节应该代表什么--所有非重要字节都被省略,这些字节的数量存储在序列化产品的最小字节中。因此,...

auto a = float{1.234}; auto width = int{7}; IC(IC_("*<",width,".3", a));Will have as result a formatting string "*<7.3", and will print:ic| a: 1.23*** Just for completeness in the examples, an usage of IC_FA and IC_FV would be:IC_FA("#x", my_function, 10, 20...
I'm trying to pass a buffer of float2 items from CPU to GPU. In the kernel, I can provide a parameter for the buffer: device const float2* values for example. How do I specify float2 as the type for the MTL::Buffer? I managed to get the code to work by "cheating" by defining...
