Method Detail

formatBytes

public static String formatBytes(long bytes)

Format bytes into a rounded string representation using IEC standard (matches Mac/Linux). For hard drive capacities, use @link formatBytesDecimal(long). For Windows displays for KB, MB and GB, in JEDEC units, edit the returned string to remove the 'i' to display the (incorrect) JEDEC units.

Parameters:

bytes - Bytes.

Returns:

Rounded string representation of the byte size.

formatBytesDecimal

public static String formatBytesDecimal(long bytes)

Format bytes into a rounded string representation using decimal SI units. These are used by hard drive manufacturers for capacity. Most other storage should use formatBytes(long).

Parameters:

bytes - Bytes.

Returns:

Rounded string representation of the byte size.

formatHertz

public static String formatHertz(long hertz)

Format hertz into a string to a rounded string representation.

Parameters:

hertz - Hertz.

Returns:

Rounded string representation of the hertz size.

formatValue

public static String formatValue(long value,
                                 String unit)

Format arbitrary units into a string to a rounded string representation.

Parameters:

value - The value

unit - Units to append metric prefix to

Returns:

Rounded string representation of the value with metric prefix to extension

formatElapsedSecs

public static String formatElapsedSecs(long secs)

Formats an elapsed time in seconds as days, hh:mm:ss.

Parameters:

secs - Elapsed seconds

Returns:

A string representation of elapsed time

round

public static float round(float d,
                          int decimalPlace)

Round to certain number of decimals.

Parameters:

d - Number to be rounded

decimalPlace - Number of decimal places to round to

Returns:

rounded result

getUnsignedInt

public static long getUnsignedInt(int x)

Convert unsigned int to signed long.

Parameters:

x - Signed int representing an unsigned integer

Returns:

long value of x unsigned
