• 1023 bytes will appear as 1023 B
• 1024 bytes will appear as 1.0 KiB
• 500000 bytes will appear as 488.3 KiB
• 1048576 bytes will appear as 1.0 MiB

The format locale will be set to the one as obtained by Faces.getLocale().

Parameters:

bytes - The bytes to be formatted.

Returns:

The formatted bytes.
