var num = 10;
var result = num.toFixed(2);

This a very common problem I see someone has already answered, I want to add to it, if you want to further use the number after conversion for calculations Try this in console
这是一个很常见的问题，我看到有人已经回答了，我想补充一下，如果您想进一步使用转换后的数字进行计算，请在控制台中尝试此操作
a = 10.2222;
typeof a /*"number"*/
a /*10.2222*/
b = parseFloat(b).toFixed(2);
typeof b /*"String"*/
b /*"10.22"*/
c = parseFloat(c)
typeof c /*"number"*/
c /*10.22*/
Explanation is-
解释是——
toFixed() method outputs a string variable
but if you want to further use the value of b as a 'number'
you will have to,
c = parseFloat(b)
typeof c
// "number"

Just add toFixed(2)here with your variable.
只需在toFixed(2)此处添加您的变量即可。
