how to get point after value in js code example

Example 1: javascript convert string to 2 decimal

var twoPlacedFloat = parseFloat(yourString).toFixed(2)

Example 2: round number to 2 symbols after comma

let num = Number(0.005) // The Number() only visualizes the type and is not needed
let roundedString = num.toFixed(2); // => "0.01"
let rounded = Number(roudedString); // => 0.01
// toFixed() returns a string (often suitable for printing already)
