How to deal with floating point number precision in JavaScript?
To handle floating point number precision in JavaScript, use the toPrecision() method. It helps to format a number to a length you can specify.
Example
<!DOCTYPE html>
<html>
<body>
<script>
var num = 28.6754;
document.write(num.toPrecision(3));
document.write("<br>"+num.toPrecision(2));
document.write("<br>"+num.toPrecision(5));
</script>
</body>
</html>Output
28.7 29 28.675
