rounding values ​​in javascript

Question

JavaScript

I need a script that allows rounding values.
For example:
23 in 25
52 in 50
110 in 100.
The main thing is that the number is a multiple of 25.
Maybe someone knows how? or do you have any work?

Answer 1

function round(n) {
  var func = n % 25 < 25/2 ? 
      Math.floor : Math.ceil;
  return func(n/25)*25;
}

you can think of many options. You can subtract the remainder from the division and sort it out there already ... The task is really elementary.

Answer 2

Call your 5th-6th grade math teacher. She will be pleased, and you will fill in the gaps in the division operations with remainders!)
