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.

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 = ={
