Many technicians can easily discuss the details of DB2 technology and confidently talk about query parallelism, data compression, WebSphere MQ integration, large object management, JDBC and ado.net drivers, data sharing on mainframe Parallel Sysplex, DB2 for Lin UX, Unix, and Windows (LUW) multidimensional clusters, and so on. But what happens if the person who talks is a member of the management? The main

It is the result of Lua's computation. We can see that the computation result is very accurate. It is the calculation result of Python3. We can see that the calculation result is inaccurate: the decimal computation in JavaScript is also inaccurate. Why is the decimal computation result often inaccurate in JavaScript? Shanzhi gave the answer to this question: in the computer,

Convert decimal to binary:The result is 1 after 2 rounds.Write the remainder and the last 1 in descending order as the result.For example, 302302/2 = 151 + 0151/2 = 75 + 175/2 = 37 + 137/2 = 18 + 118/2 = 9 + 09/2 = 4 + 14/2 = 2 + 02/2 = 1 + 0The binary value is 100101110. Convert binary to decimalStart from the last digit and column it as 0th, 1, 2...The number (0 or 1) of the nth digit multiplied by the Npower of 2The result is the answer.Example: 01
