I want to calculate 17% from 835 and after reduce from n the resulted number.
But the resulted number is 693.5 and I want to show downwards to the nearest integer 693.
The Math.floor should do that but I don't understand why the resulted number shown is 694.
Thank you.
function compute_active_users(n, b) {
// Write your code here
var s =b/100*n;
var b =Math.floor(s);
console.log(n-b);
}
compute_active_users(835,17);

Okey you should do
function compute_active_users(n, b) {
// Write your code here
var s = b /100 *n;
var b = Math.floor(n - s);
console.log(b);
}

When i use 'alert',it works perfectly.. but i want to use sweet alert and it is not display anything via sweet alert. when i do:
function myfunc(size){
sweetAlert(size );
it does display the size using the code above. the problem is, it doesn't work when i try to perform the addition. why is it so?
try something like this
import swal from "sweetalert";
function myfunc(size) {
var m = parseInt(size) + 5;

I want to figure out what return -1 and return 1 did in following code
https://www.w3schools.com/js/tryit.asp?filename=tryjs_array_sort_object2
If car a is in lower alphabetical order than car b then -1 is returned, if it is higher then 1 is returned, and if they are the same then 0 is returned.
Given a sorting criterion, let us consider lexicographical ordering, there can only be three conditions that exist between two letters/number, a and b.
The condition are as follows:
a = b/both are equal, return 0
a < b or a occurs before b, return -1
a > b or a occurs after b, return 1

if(MathRScore > 29.9 && MathRScore < 34.9 ) MathScore = 10*Math.round((MathRScore*45/5+(535*35-580*30)/5)/10);
I've inherited this tiny line of exception code for a scoring algorithm I'm maintaining. I'm not sure what it does exactly. Can someone walk me through it?
If your MathRScore is in the interval (29.9, 34.9) then set the MathScore to (in simplified form)
MathScore = 10*Math.round((MathRScore*9+265)/10)
By dividing by 10, then using Math.round and then multiplying by 10 you will round to the nearest ten.
For example
10*Math.round(1111/10) = 10*Math.round(111.1) = 10*111 = 1110
if the value of MathRScore is between 30 and 34.8 , it will make the variable MathScore hold the value of 10 times the rounded value of all that stuff in the parenthesis.
If MathRScore is between 29.9 and 34.9, exclusive, then set MathScore to the value:
(MathRScore * 9) + 265
rounded to the nearest 10.
Beyond that, what this means can only be revealed by understanding how these scores work, and we can't tell you that.
