If you found this question and like me you are looking for a way to do this in JavaScript, then you might find this useful.

getDeviceFamilyVersion() {
    let deviceFamilyVersion = Windows.System.Profile.AnalyticsInfo.versionInfo.deviceFamilyVersion;
    let deviceFamilyVersionDecimalFormat = parseInt(deviceFamilyVersion);

    if (isNaN(deviceFamilyVersionDecimalFormat)) {
        throw new Error('cannot parse device family version number');
    }

    let hexString = deviceFamilyVersionDecimalFormat.toString(16).toUpperCase();

    while (hexString.length !== 16) { // this is needed because JavaScript trims the leading zeros when converting to hex string
        hexString = '0' + hexString;
    }

    let hexStringIterator = 0;
    let versionString = '';
    while (hexStringIterator < hexString.length) {
        let subHexString = hexString.substring(hexStringIterator, hexStringIterator + 4);
        let decimalValue = parseInt(subHexString, 16);

        versionString += decimalValue + '.';
        hexStringIterator += 4;
    }

    return versionString.substring(0, versionString.length - 1);
}
