I want to divide 1000/3 as an example and set the answer into an input.
my problem is that I don't want them to be float , so I rounded the like this
const answer = Math.round(1000/3);
When I set them in 3 inputs all are 333 and the answer of their sum is 999 but I want one of them to be 334 and the others 333 How can I handle that generally? Thanks for your help
i want one of them to be 334 and the others 333
Just add one to 1000 to be 1001 so:
let s1 = Math.round(1000/3); //333
let s2 = Math.round(1000/3); //333
let s3 = Math.round(1000/3); //333
console.log(s1+s2+s3); //999
let s4 = Math.round(1001/3); //334
console.log(s2+s3+s4); //1000Here's a generic function that will split your integer k into n parts whose sum is k:
const arr = []
, splitInteger = (num, parts) => {
let sum = 0;
for (let i = 0; i < parts - 1; i++) {
const curr = Math.floor(num/parts)
arr.push(curr)
sum += curr
}
arr.push(num - sum)
}
// Splitting 1000 into 3 parts
splitInteger(1000, 3)
console.log(arr)
// Let's try 7 parts
arr.length = 0
splitInteger(1000, 7)
console.log(arr)i want one of them to be 334 and the others 333 how can I handle that generally?
How general? I'm not sure there's a perfect answer. However, based on your example, I'd use something like the following:
var input = 1000
var divisors = 3
var value = Math.round(input/divisors)
var display1 = value
var display2 = value
var display3 = input - value * (divisors-1)
console.log( display1, display2, display3 )In certain circumstances you may need to be more careful with the rounding, but for integer ranges from 0-100 this should be fine.
