Class Method Details

.nice_bytes(number) ⇒ String

Convert bytes into more human readable format. I have found nice resolution here

which was originally written by Jeff Emminger and I just add this part
to automaticly set the unit. Thank you, Jeff!

Parameters:

  • number (Integer) —

    of bytes to be formatted

Returns:

  • (String) —

    a formatted number with the unit appended to it
