I'd like to do a "rounding" of values within the javascript.
I know that the Math.Round() function rounds, but only decimal, I need the following situations.
1 - 10 in 10 ... If the user types 155, the system rounds to 160, If the user types 152 for example, the system rounds to 150.
2 - From 500 in 500 ... If the user types 4300, the system rounds to 4500, if the user types 4220, the system rounds to 4000
I honestly have no idea how to do this.
Thank you in advance
Use the same Math.Round() but round in relation to the order of magnitude you want:
function arredondaPorOrdem(nr, ord) {
return Math.round(nr / ord) * ord;
}
var decimas = arredondaPorOrdem(153, 10);
var cincoEmCinco = arredondaPorOrdem(153, 5);
console.log(decimas, cincoEmCinco); // 150 155Divide the number by 10, round the result and multiply by 10 again:
var number = 33;
alert(Math.round(number / 10) * 10);
With 500 is logic is similar
In 500 it would look like this:
var number = 1003;
alert(Math.round(number / 500) * 500);
I think this function would solve your problem:
function arredondar(num) {
if (num <= 500) {
return Math.round(num / 10) * 10;
} else {
return Math.round(num / 500) * 500;
}
}
arrendondar(4440);
