Utility Function for Rounding to Significant Digits in TypeScript

I frequently find myself formatting numbers by rounding to some number of digits. I often have to write a utility function like:

const roundTo = (digits: number, value: number) => Math.round(value * (10 ** digits)) / (10 ** digits)

const roundTo = (digits: number, value: number) => Math.round(value * (10 ** digits)) / (10 ** digits)

Today I thought to look to see if effect had a similar functionality but didn't find it. Would that be a useful addition?
