Sebb commented on IO-294:
-------------------------
Looks useful; however I'm not sure FileUtils is the correct place for it, as
bytes are also used for network sizes, etc.
The main part of the code purely deals with numbers, and is not specifically
related to IO - perhaps it belongs in Lang?
> Adding FileUtils.byteCountToDisplaySize(long size, boolean useSiUnits)
> ----------------------------------------------------------------------
>
> Key: IO-294
> URL: https://issues.apache.org/jira/browse/IO-294
> Project: Commons IO
> Issue Type: New Feature
> Components: Utilities
> Affects Versions: 2.1
> Reporter: Jean-Noel Rouvignac
> Fix For: 2.2
>
> Attachments: FileUtils.java, FileUtilsTest.java
>
>
> I have written a little Utility method that might benefit Commons IO:
> {code}
> public class FileUtils {
> /**
> * Returns a human-readable version of the file size (original is in
> bytes). The implementation has the following features:
> * <ul>
> * <li>Supports the SI or IEC units.</li>
> * <li>Supports I18n</li>
> * <li>Display a one digit remainder (rounded down if less than 5,
> rounded up otherwise)</li>
> * <li>Once the main unit is >= 100, drops the remainder which would be
> over precision.</li>
> * </ul>
> *
> * @param size The number of bytes.
> * @param useSiUnits if false, uses the IEC (International
> Electrotechnical Commission) units (powers of 2), else uses SI (International
> System of Units)
> * units (powers of 10).
> * @return A human-readable display value (includes units).
