    Description

      See: https://en.cppreference.com/w/cpp/io/manip/fixed
      It's a standard format in the C++ world, so we should at least consider supporting it.
      The format is floating-point, with a hexadecimal mantissa (with "0x" prefix) but a binary exponent, using "p" as the exponent separator.
