Please restrict all scores to only one decimal point and ensure that all integer scores include a ".0" at the end, except for scores of 10 or 0

Question

Please restrict all scores to only one decimal point and ensure that all integer scores include a ".0" at the end, except for scores of 10 or 0

Ensure scores are rounded to a single decimal point and update all integer values with .0, except for 10 and 0.

For example:

0.972 should be 0.9
2.83 should be 2.8

All integer scores will be updated as:

0
1.0
2.0
3.0
4.0
5.0
6.0
7.0
8.0
9.0
10

I have used regular expressions to handle the single digit after the decimal point:

parseFloat(pillarScore.match(/^-?\d*(?:\.\d{0,1})?/)[0]);

However, I am now working on obtaining the correct updated integer part instead of returning numbers like 1, 2, 3, etc.

Answer №1

If you need to format a number with a specific character length after the decimal point, you can utilize the toFixed method in JavaScript. Additionally, the remainder operator can be used to determine if a number is divisible by 10.

function formatNumber(n) {
  return n % 10 ? (parseInt(n * 10) / 10).toFixed(1) : n;
}

console.log(formatNumber(0));
console.log(formatNumber(1));
console.log(formatNumber(3));
console.log(formatNumber(10));
console.log(formatNumber(0.972));
