I want my number to always get rounded to the closes upper number like this:
1.2 => 2
1.4 => 2
Use Math.ceil():
Math.ceil(1.2); // 2
You can use the Math.ceil()
function.
Math.ceil(1.1) // returns 2
Conversely, if you wanted to round down you'd use Math.floor()
Math.floor(1.8) // returns 1
Here's a demo:
console.table([1, 1.25, 1.49, 1.5, 1.75, 2].map(n => ({
n,
["Math.floor(n)"]: Math.floor(n),
["Math.ceil(n)"]: Math.ceil(n),
["Math.round(n)"]: Math.round(n),
})));

Note: Floor and ceiling functions aren't exclusive to javascript. See this wikipedia entry for more info.
Use Math.ceil()
It does exactly what you want.
I use Math.ceil()
function for round upper value.
