Method Detail

byteCountToDisplaySize

public static String byteCountToDisplaySize(BigInteger size,
                                            int maxChars)

Adopted and improved version of FileUtils.byteCountToDisplaySize(BigInteger).

Warning! it is not advised to use maxChars < 3 because it produces correctly rounded, but non-intuitive results like "0 KB" for 100 bytes.

• https://issues.apache.org/jira/browse/IO-226 - should the rounding be changed?
• https://issues.apache.org/jira/browse/IO-373

Parameters:

size - the size in bytes

maxChars - maximum length of digit part, ie. '1.2'

Returns:

rounded byte size as String

public static String byteCountToDisplaySize(BigInteger size)

byteCountToDisplaySize

public static String byteCountToDisplaySize(long size,
                                            int maxChars)

See byteCountToDisplaySize(BigInteger,int).

Parameters:

size - the size in bytes

maxChars - maximum length of digit part, ie. '1.2'

Returns:

formatted size suitable for display
