�Zd�Zed��ZRS(s�Represents the size of an object such as a disk partition.

  Conversions are provided to and from suffixed size strings as used
  by LVM commands like lvcreate(8). These strings consist of a
  (possibly floating-point) number followed by an optional unit
  suffix: B (bytes), S (512-byte sectors), and KMGTPE for kilobytes
  through exabytes, respectively. Suffixes are not case-sensitive; the
  default unit is Megabytes. Currently, we reject negative sizes.

  Unlike some (but not all) LVM commands we do not interpret the upper-case
  version of a suffix as a power of ten.

  Attributes:
    _originalString (str): the original string we were constructed
      with, mainly used for debugging
    _bytes (int): the value of this object in bytes
