arithmetic operations on floating point numbers

Http://www.cnblogs.com/kingwolfofsky/archive/2011/07/21/2112299.html floating point numbers 1. What are floating point numbers In the process of computer system development, several methods have been proposed to express real numbers. Typically, for

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. Transferred from: http://www.cnblogs.com/kevinq/p/4480563.html Reference: 1.http://www.

1 representation of floating-point numbersIn general, we can use the following format to represent floating-point numbers S P M where S is the sign bit, p is the order, M is the mantissaFor IBM-PC, a

One: Floating-point simulators on early arm: Early arm does not have a coprocessor, so floating-point operations are simulated by the CPU, where floating-point operations are performed on floating-point arithmetic simulators (float math emulation),

1. arithmetic operation points (1) shift operation ① Original code shift: the original code does not change the form of the original code when performing arithmetic shift left or arithmetic shift right. Shifts one digit to the left is equal to
