  // This is the beginning of the preamble.

  // In this preamble, the preprocessor is used to query certain
  // preprocessor definitions from <float.h>. Based on the results
  // of these queries, an attempt is made to automatically detect
  // the presence of built-in floating-point types having specified
  // widths. These are *thought* to be conformant with IEEE-754,
  // whereby an unequivocal test based on std::numeric_limits<>
  // follows below.

  // In addition, various macros that are used for initializing
  // floating-point literal values having specified widths and
  // some basic min/max values are defined.

  // First, we will pre-load certain preprocessor definitions
  // with a dummy value.
