• possible duplicate of Round money to nearest 10 dollars in Javascript, take out the money factor and the fact that question is for tens instead of hundreds and the question is the same. Even the answers are identical. – Andy E Commented Jan 30, 2012 at 9:06

function roundHundred(value){
   return Math.round(value/100)*100
}

Live example with your test cases: http://jsfiddle.net/LaPGs/

you can divide it by 100 first then use Math.round, and finally multiply it by 100.

> Math.round(10651.89 / 100) * 100
10700

we can use Math.ceil for doing this.

var rawNumber = 10651.89;
 roundFigure= Math.ceil(rawNumber /100)*100

function(x) {
  return Math.round(x / 100) * 100;
}
