I have a specific number that constantly changes and currently looks like this:
800.60000305176541
Every time the number updates, I use the following code:
var mynumber = 800.60000305176541
var changenumber = mynumber.toFixed(3);
The output shows as 800.600, but what I really need is to display only the last three digits like this:
800.541
Could someone please advise on how to achieve this?
If you need to perform operations on a number that is too large for JavaScript, you can convert it to a string first. Keep in mind that there may be precision loss when dealing with very large numbers.
var num = 900.70000305176541;
var strNum = "" + num;
var splitNum = strNum.split(".");
var resultNum = splitNum[0];
if (splitNum[1]) {
resultNum += "." + splitNum[1].slice(-3);
}
console.log(num);
console.log(resultNum);Perhaps another approach could be to attempt a mathematical solution.
