  // The mebibyte is a multiple of the unit byte for digital information. Technically a
  // megabyte (MB) is a power of ten, while a mebibyte (MiB) is a power of two,
  // appropriate for binary machines. Many Linux distributions use the unit, but it is
  // not widely acknowledged within the industry or media.
  // Reference: https://en.wikipedia.org/wiki/Mebibyte
  //
  // Examples:
  // 	auto size1 = EA_KILOBYTE(16);
  // 	auto size2 = EA_MEGABYTE(128);
  // 	auto size3 = EA_MEBIBYTE(8);
  // 	auto size4 = EA_GIBIBYTE(8);
