javascript multiplication

JavaScript in the multiplication of floating-point numbers, there will be a number of decimal places.This is because in the operation of the first floating-point number into binary after the operation, but some decimal in the binary code after the infinite loop, resulting in the calculation of errors, and other into the language has similar problems.Reason explanation reference since Baidu knows:For example

CSS Code section: 1 style type = "Text/css" > 2 table { 3 width:800px; 4 height:300px; 5 Border-collapse:collapse; 6 7 td{border:1px solid red;} 8 Style > JS Code section:1 ScriptTjpe= "Teit/javascript">2document.write ("Table>");3 var str = "JS 99 multiplication table";4document.write ("H1>"+ str +"H1>");5for (var i = 1; i= 9; i++) {6 document.write (">");7for (var j = 1; j= i; j

This article describes in detail how to implement the multiplication table based on javascript. If you are interested, refer to the examples in this article and share the code for javascript to implement the multiplication table, the details are as follows:

Every person who has ever studied programming has written "HelloWorld." But the 99 multiplication table, I think, should also be a necessary program for every programming beginner. This is the implementation of JavaScript, very suitable for beginners!!! The following are code and comments Here are some of the things that are covered in the code above The Border= the "" property to set t

Example 1 The basic idea is to turn the floating-point numbers into integers and divide them by the N-order of the equivalent 10. n is (the sum of the back lengths of two floating-point numbers). code is as follows copy code function FXF (f1, F2) { f1 + = '; F2 + + '; var f1len = f1.spli T ('. ') [1].length, f2len = F2.split ('. ') [1].length; if (f1len) { f1 = F1.replace ('. ', '); nbsp;} if (f2len) { F2 = F2.replace ('. ', ' ); } Return F1

Baidu Google did not find "javascript two-dimensional matrix multiplication", then I will write a share to everyone. (I wrote the multiplication of two n*n two-dimensional matrices)The following is the time to paste the code:function Matrixmultiplication (A, b) { var len=a.length,arr=[]; for (Var i=0;iIn addition, we recommend a JS great God's writing:functi

In Ruby, the "*" operator used with a string on the left and a number on the right does string repetition. "Ruby" * 2 evaluates to "RubyRuby", for example. this is only occasionally useful (when creating lines of hyphens for ASCII tables, for example) but it seems kind of neat. and it sure beats having to write a loop and concatenate n copies of a string one at a time -- that just seems really inefficient.I just realized that there is a clever way to implement string

Address: http://www.davidflanagan.com/2009/08/string-multipli.htmlOriginal Author: David FlanaganIn Ruby, the "*" operator uses a string as the left parameter and a number as the right parameter to implement string duplication. For example, the value of "Ruby" * 2 is "rubyruby ". This is useful only in a few places (for example, generating a table consisting of ASCII characters such as hyphens), but it is very concise. It is much less efficient than writing a loop to connect strings for n times.

1. Print 99 multiplication table function Chengfa () { // repeatedly call formula for (var r=1;r) { for (var i=1,str= ""; i) { str=str+ (i+ "x" +r+ "=" +i*r+ "\ T") ; } Console.log (str); } } CHENGFA ();2.

Javascript (js) decimal point addition, subtraction, multiplication, division, is a js bug such as 0.3*1 = 0.2999999999, the following lists the four js algorithms that can perfectly find the corresponding precision // division function accDiv (arg1, arg2) {var t1 = 0, t2 = 0, r1, r2; try {t1 = arg1.toString (). split (". ") [1]. length} catch (e) {}try {t2 = arg2.toString (). split (". ") [1]. length} catc

Examples of this article to share the JavaScript implementation of the 99 multiplication table related code, the specific contents are as follows The implementation results are as shown in the figure: I hope this article will help you learn about JavaScript programming.

The University major is computer shoes or many or small ones know that computers store and process numbers in binary format. They cannot be precise to floating point numbers, and javascript does not have such a method, so there will be errors during browser computing. For example, if I want to use 3.3/1.1, the answer is 3, no, but we can print out the results. We are surprised that it is 2.9999999999999996. now we want to avoid precision differences,

In this paper, we illustrate the method of JavaScript realization of trapezoidal multiplication table. Share to everyone for your reference. Specifically as follows: The effect is shown in the following illustration: The table is table,tr,td in HTML and then implemented with a for statement, loops out rows and columns, multiplies by the number of ranks, the first for loop outputs 9 rows, and then insert

Multiplying floating-point numbers in JavaScript is a fun thing to do. There are many ways to multiply floating-point numbers, and here's a solution that I think is good for me: Copy Code code as follows: function fxf (f1, F2) { F1 + = '; F2 + = '; var F1len = F1.split ('. ') [1].length, F2len = F2.split ('. ') [1].length; if (F1len) {F1 = F1.replace ('. ', ');}if (F2len) {F2 = F2.replace ('. ', ');}Return F1 * F2/MATH.POW (F1len + F2

Let's take a look at the effect chart.
