numberToHumanData

public static String numberToHumanData(Number number,
 short precision,
 Locale locale)

Takes a Number with bytes and returns it as a formatted SI (metric) multiple-byte number.

Inspired by https://stackoverflow.com/a/3758880/1074188.

Parameters:

number - number containing size in bytes

precision - Sets the precision of the number. Value -1 has a special meaning here: an absolute formatted number less then 10 results in precision 2; an absolute formatted number less then 100 results in precision 1; all other absolute formatted numbers result in precision 0

locale - The locale to apply during formatting. If locale is null then no localization is applied.

Returns:

the formatted SI (metric) multiple-byte number

Throws:

IllegalArgumentException - if precision is less than -1
