Thefloatdata type is utilized in C and C++ programming to hold floating-point values, which can either be decimal or exponential. You must use the%fspecifiers with the float data type variable to output them on the console screen for the case of C programming. While for C++, there are no...
Note:If we specify the precision greater than the precision of the data type itself (7 forfloatand 15 fordouble), then the compiler will give us garbage values after the precision limit has been exceeded, as can be seen with thefloatoutput inexample 2. Work with Exponential Numbers As ment...

Inside the loop, we perform the type conversion using a C-style cast: int(f).As we can see in the output, this cast converts the floating-point number f to its integer representation.In practice, when possible, it’s better to use more type-safe casting mechanisms provided by C++, ...

kernel位置在aten/src/ATen/native/cpu/MaxPoolKernel.cpp 缓存输入数据 如果我们需要多次访问输入数据,有个时候可以把输入数据先缓存成float32,这样可以省掉后续的dtype转换。一般要注意缓存数据的大小,要能对L1命中。 下面这个例子是优化LayerNorm在BFloat16上的性能的,采取了这个策略:#71376 /* Example-5: cache...
