Math.round(x*100)/100, of course what I want is Math.round(x*100), it doesn’t matter. But there is a problem with using Math.round(x*100) directly. Sometimes there is a small error, and many decimal places are displayed. For example, 0.9996*100 will become 99.96000000000001, which is not what I want.

Find the function of javascript, the number type has a toFixed() function, test:

Copy code The code is as follows :

alert((0.9996*100).toFixed(2));

Use Number.toFixed() to format numbers to display any decimal places!
