@numio/bigmath/src/mean/mean.js

@numio/bigmath is an arbitrary-precision arithmetic library. It can be used for basic operations with decimal numbers (integers and float)

import { bi2s, s2bi } from "../shared/utils.js";
import { meanInner } from "./utils.js";
/** This function returns mean of an array. */
export const mean = (array) => {
    const arrayInner = Array(array.length);
    for (let i = 0; i < array.length; i++) {
        arrayInner[i] = s2bi(array[i]);
    }
    const bi = meanInner(arrayInner);
    return bi2s(bi);
};
