Use Math.ceil(), if you want to always round up:
Math.ceil(number/100)*100

To round up and down to the nearest 100 use Math.round:
Math.round(number/100)*100
round vs. ceil:
Math.round(60/100)*100 = 100vs.Math.ceil(60/100)*100 = 100
Math.round(40/100)*100 = 0vs.Math.ceil(40/100)*100 = 100
Math.round(-60/100)*100 = -100vs.Math.ceil(-60/100)*100 = -0
Math.round(-40/100)*100 = -0vs.Math.ceil(-40/100)*100 = -0

This will do what you want:
Math.round(value/1000)*1000
examples:
Math.round(1001/1000)*1000
1000
Math.round(1004/1000)*1000
1000
Math.round(1500/1000)*1000

By using ES3 Number method, it performs a rounding if no decimal place defined.
(value / 1000).toFixed() * 1000
The original answer was:
(value / 1000).toFixed(3) * 1000;
Yet this is incorrect, due to the value will return the exact original number, instead of affecting the ceil/floor on the value.

Method 1: The quick way is to use toFixed() method like this:
var num = 2.12;
var round = num.toFixed(1); // will out put 2.1 of type String
One thing to note here is that it would round 2.12 to 2.1 and 2.15 to 2.2
Method 2: On the other hand you can use Math.round with this trick:
var num = 2.15;
Math.round(num * 10) / 10; // would out put 2.2
It would round to the upper bound.
So, choose whichever you like.
Also if you use a modern version of JS ie. ES then using const and let instead for variable declaration might be a better approach.
NOTE: remember that .toFixed() returns a string. If you want a number, use the Math.round() approach. Thanks for the reminder @pandubear
