divide number with decimals javascript

Question

how can I divide number (money) to x number equally the number could be with one or two decimal or without it

such as 1000 or 100.2 or

Answer 1

Sounds like a pretty straightforward loop/recursion.

Here you go

function divideEvenly(numerator, minPartSize) {
  if(numerator / minPartSize< 2) {
    return [numerator];
  }
  return [minPartSize].concat(divideEvenly(numerator-minPartSize, minPartSize));
}

console.log(divideEvenly(1000, 333));

To get it to be two decimals of currency multiply both numbers by 100 before calling this function then divide each result by 100 and call toFixed(2).

Like so

function divideCurrencyEvenly(numerator, divisor) {
  var minPartSize = +(numerator / divisor).toFixed(2)
  return divideEvenly(numerator*100, minPartSize*100).map(function(v) {
    return (v/100).toFixed(2);
  });
}


console.log(divideCurrencyEvenly(3856, 3));
//=>["1285.33", "1285.33", "1285.34"]

Answer 2

<button onclick="myFunction(3856,3)">Try it</button>

function myFunction(number,divide) {
        var money = number / divide;
        money = Math.ceil(money * 100) / 100;
        alert(money);   //1285.34
    }
