在JavaScript中小数点后加0

Question

I have searched through a lot of threads and all of them give the same answer.

I am trying to add 0s right after the decimal point to an integer. If I have var a = 25. I want to modify a such that its value is 25.0. Most of the offered solutions either suggest appending a string ".0" or using .toFixed() which appends any number of 0s you want but still returns a string. I want the response to be float number and not a string.

Any thoughts on how I could achieve this?

Thanks.

It has been a while since someone used this thread, but just in case someone needs it I think the answer you are looking for is:

.toFixed(2)

Example:

let number = 4;
return number.toFixed(2) //4.00
