      • formatToMeBi

        public static java.lang.String formatToMeBi​(long number)
        Formats number to Mebibytes (g/m only) without fractions and bytes as base unit. For input outside the m/g range, the input is returned. Please be aware of number overflow for larger g values. [public for testing]
        Parameters:
        number - the number to be formatted
        Returns:
        the formatted number

                                            int baseUnit)
        Formats number to Mebibytes (g/m only) without fractions. For input outside the m/g range (including t in terms of g), the input is returned. [public for testing]
        Parameters:
        number - the number to be formatted
        baseUnit - 0 = bytes, 1 = kByte, 2 = mByte, 3 = gByte, ...
        Returns:
