Answers for "round to nearest multiple of 5 javascript"

rounding up a number so that it is divisible by 5 javascript

function round5(x)
{
    return Math.ceil(x/5)*5;
}

javascript round to nearest 10

var rounded = Math.round(number / 10) * 10

get nearest multiple of a number javascript

/*
	Gets the nearest multiple of a given number.
    
    @param {Number} number The number to go up from.
    @param {Number} multiple The base to get the multiple of.
*/
function getNearestMultiple(number, multiple)
{
	return number + (multiple - (number % multiple));
}

/* example code below (very repetitive, but you don't need to copy it) */

var num1 = 1;
var num2 = 4;
var num3 = 6;
var num4 = 8;
var num5 = 13;
var num6 = 12;
var num7 = 14;
var num8 = 19;
var num9 = 21;

console.log(`\nNumber: ${num1}\nBase: 2\nNext Multiple: ${getNearestMultiple(num1, 2)}`);
console.log(`\nNumber: ${num2}\nBase: 3\nNext Multiple: ${getNearestMultiple(num2, 3)}`);
console.log(`\nNumber: ${num3}\nBase: 4\nNext Multiple: ${getNearestMultiple(num3, 4)}`);
console.log(`\nNumber: ${num4}\nBase: 5\nNext Multiple: ${getNearestMultiple(num4, 5)}`);
console.log(`\nNumber: ${num5}\nBase: 6\nNext Multiple: ${getNearestMultiple(num5, 6)}`);
console.log(`\nNumber: ${num6}\nBase: 7\nNext Multiple: ${getNearestMultiple(num6, 7)}`);
console.log(`\nNumber: ${num7}\nBase: 8\nNext Multiple: ${getNearestMultiple(num7, 8)}`);
console.log(`\nNumber: ${num8}\nBase: 9\nNext Multiple: ${getNearestMultiple(num8, 9)}`);
console.log(`\nNumber: ${num9}\nBase: 10\nNext Multiple: ${getNearestMultiple(num9, 10)}`);

// output

best way to round to two typescript

const roundTo = function(num: number, places: number) {
  const factor = 10 ** places;
  return Math.round(num * factor) / factor;
};

roundTo(123.456, 2);  // 123.46
roundTo(123.3210, 2);  // 123.32
roundTo(123.456, 1);  // 123.5
roundTo(123, 2);  // 123
