  15 // Integer radix display representations:
  16 //   There are three ways in which the radix is represented:
  17 //     - none - the number is just printed as a number (e.g. 12345). Can be confusing for non-decimal radix
  18 //     - C style - for binary, octal and hex, the C-style prefices 0b, 0 and 0x are used
  19 //       note that this is an unsigned representation
  20 //     - Hash style - in the form radix#value - the value may be signed, e.g. 10#-9

  33 // There are three formats for the printout:
  34 //   - fixed - formatted as a fixed-point number, so no mantissa is printed (equivalent to %f in printf)
  35 //   - floating - formatted as a normalised floating-point number (equivalent to %e in printf)
