I have this integer
I have a variable that tells me this number should have n decimal places (In this case 18)
How can I change it to 7.839486009458047182
(If React has this as a method I could use in a template that’s even better!)
If you’re not too bothered about precision, you can simply divide the integer by
10 ** decimals, for example:
console.log(7839486009458047182 / (10 ** 18)); // ^ 7.839486009458047
Mind that floats have limited precision. If precision is key, keep it as an integer (or bigint). If it’s just for display purposes, then a small amount of imprecision shouldn’t be an issue.
