I\'m very new to html, javascript, and css so please forgive if my question sounds idiotic to you. My question is how can I prevent the function toFixed() from

Answer 1

you can give this a try, it won't round your decimals

/**
 * @param {any} input 
 * @param {number} decimals 
 */
var toFixed = function(input, decimals) {
  var arr = ("" + input).split(".");
  if (arr.length === 1) return input;
  var int = arr[0],
      max = arr[1].length,
      dec = arr[1].substr(0, decimals > max ? max : decimals);
  return decimals === 0 ? int : [int, "." , dec].join("");
}
