To solve the Bug in JS floating point operations, you can refer to 37.5*5.5 = 206.08 (JS calculates this result, and I rounded it to two decimal places) I first suspected it was a rounding problem, and I used JS to calculate a result: 206.08499999999

Javascript (js) decimal point addition, subtraction, multiplication, division, is a js bug such as 0.3*10.2999999999. The following lists the four js algorithms that perfectly match the accuracy. // division functionaccDiv (arg1, arg2) {vart10, t20,

(Workaround one: a function that overrides a floating-point operation)The Division function, which is used to get accurate division results.Description: The result of the division of JavaScript will be error, which will be obvious when dividing two

There is an error in the division result of javascript, which is obvious when two floating point numbers are separated. This function returns a more precise division result. The Code is as follows: // Division function, used to obtain accurate

Here are some of my usual JS validation and functions, there are some validation I write directly to the object's properties, you can directly through the object. method to invokeFloating-point division operation function Fdiv (A, B, n) {if (n = =

Because JS multiplication and add and subtract operations sometimes have the problem of loss of precision, at the same time, two non-numeric addition will also appear the problem of type conversion, so specifically wrote a arithmetic JS not lost

I. Events Recently, the project management fee was written in JS on the client. A major problem was found, such as 0.7*8.1 = 5.6699999999, 10.3-9.2 = 100000000014. Why are these problems? Is it a bug in JS's floating point operations? What should

After four years of web development, I have accumulated more or less JavaScript scripts. For example, to restrict input to scripts that only allow numbers to be input, and press enter to automatically go to the next control, which is equivalent to

Writing an article: I am no longer familiar with Ajax skills (reprinted). maybe it is (ActiveJavascriptActionXml, to put it bluntly, javascript, xmlhttp, and xmldom techniques and website background are used for processing. Writing articles:

The problem is as follows: 37.5*5.5 = 206.08 (JS calculates this result, and I rounded it to two decimal places). I suspected it was a problem, the result is calculated by using JS: 206.08499999999998. How can we multiply two digits with only one

JavaScript has only one numeric type Number, and all numbers in Javascript are represented in IEEE-754 standard format. The precision of floating point numbers is not unique to JavaScript, because some decimals represent infinite digits in binary
