I learned a bit about it today. Adding and subtracting with bitwise arithmetic because negative numbers are stored in a way that is complementary, the addition is realized by subtraction.The addition operation is based on a theorem such as:A + b = a^b + ((A B) It's good to go back to the point of rounding or zero.Code:1#include 2#include 3#include 4 using namespacestd;5 6 int Get(intAintb) {7 intc = a

ThinkPHP User-Defined Function solves the method of adding and subtracting template labels. thinkphp Template This example describes how ThinkPHP UDF solves the addition and subtraction of template labels. Share it with you for your reference. The details are as follows: In actual projects, we often need to add or subtract tag variables. However, in ThinkPHP, direct operations on Template variables are no

1. Questions:This happens in the usual code, and the result of parsefloat (11.3-10.1) operation is still 1.200000000000001.code example:var arr = [0.0111,11.002,0.3,1.5,1.61var 0 = ={ + + Item }) Console.log (total) The result of the return---14.423100000000002, which is illogical.2. Solution:Here's a practical workaround for some floating-point application functions in math such as: parsefloat () and Math.floor ()The code is as follows:var arr = [0.0111,11.002,0.3,1.5,1.61var 0 = ={
