  10 //   Persistence of floating-point types
  11
  12 //   Note: despite years and years of IEEE standardisation, not all
  13 //   architectures use IEEE-standard representations of floating-point numbers.
  14 //   Therefore a binary dump is not necessarily portable between platforms.
  15 //   Solving this is (currently) beyond the scope of the STLplus project.
  16
  17 //   If you want to be strictly portable to all platforms, do not dump/restore float
