[jira] Created: (IO-226) question with byteCountToDisplaySize(long
size)
question with byteCountToDisplaySize(long size)
-----------------------------------------------
Key: IO-226
URL: https://issues.apache.org/jira/browse/IO-226
Project: Commons IO
Issue Type: Bug
Components: Utilities
Reporter: shu kai yuan
I do not understand the byteCountToDisplaySize(long size) method which is in class FileUtils of the package org.apache.commons.io.
If the parameter size is 2047 , the method will return 1 KB.Why it will lose precision.
I read the code.
Maybe it is a bug?

[jira] Commented: (IO-226) question with
byteCountToDisplaySize(long size)

Sebb commented on IO-226:
-------------------------
The size is currently rounded down, so it can lose precision.
However, even if it were rounded to the nearest boundary it would still lose some precision.
In order to avoid loss of precision it would have to display the value 2047 as 1.9990234375KB which is not very readable.
For the time being, I have updated the Javadoc to note that the value is rounded down:

Log:
IO-226 - document rounding behaviour
