Discussion on: Daily Challenge #296 - Years to Centuries

[Sooraj (PS)]

const toCentury = (year) => {
  const century = Math.ceil(year / 100);
  if (century.toString().length > 2) return year + " --> " + century + "th";
  switch(century % 10) {
    case 1: return year + " --> " + century + "st";
    case 2: return year + " --> " + century + "nd";
    case 3: return year + " --> " + century + "rd";
    default: return year + " --> " + century + "th";
  }
}

Clean and elegant!

But according to the math, 1 - 100 is 1st century. So I thought 1901 - 2000 is 20th century and 2001 - 2100 is 21st century. Is my understanding wrong ?

"1066 --> 11st" should be 11th
"10266 --> 103th" should be 103rd
