First, let's talk about how to convert decimal places to binary decimal places. The computer doesn't even know the decimal data. He only knows 0 and 1. So, decimal decimal
Although almost every processor andProgramming LanguageAll support floating point operations, but mostProgramStaff seldom pay attention to it. This is easy to understand-most of us seldom need non-integer types. In addition to scientific computing

This paper is derived from quantization, data type, overflow and underflow, and the floating-point number is considered as a quantization method of real field, and the difference between floating-point number, especially irregular floating-point
First, let's look at a piece of code (in VC, in C ++ ):
int a = 2; int b = 3; int c = 6; if(1.0 / a + 1.0 / 3 + 1.0 / c >= 1.0) cout
Is yes output or no output?Answer:In the console, after several seconds, no is output.The problem arises.
At present, the parallel optimization of the CNN convolutional neural network on the hardware platform is studied, and the relevant knowledge needs to be mended.
