问题是**{fmt}**本身没有为扩展浮点类型提供任何格式化程序。尝试格式化std::float128_t将在某种程度上...
This PR Move operator<< of BFloat16 to BFloat16.h. Previously, this function is in TensorDataContainer.h. If need std::cout a BFloat16 variable when debugging, TensorDataContainer.h have to be included. This is inconvient and counterintuitive. Other dtyp
默认是shortest round-trip。要区分两个IEEE 754的double值，至多需要考虑16至17位（log10(254)）。
不过有一个领域不太需要LAPACK，那就是深度学习，正好std::float16_t,std::bfloat16_t也要进标准库...

在C++ 中,您可以使用std::stold函数将std::string转换为long double类型,这通常被认为是一种longfloat类型。以下是一个示例: cpp#include <string> #include <iostream> int main() { std::string s = "3.14159265358979323846"; long double ld = std::stold(s); ...
