-;;; Commentary:
-
-;; Floating point numbers are represented by dot-pairs (mant . exp)
-;; where mant is the 24-bit signed integral mantissa and exp is the
-;; base 2 exponent.
-;;
-;; Emacs LISP supports a 24-bit signed integer data type, which has a
-;; range of -(2**23) to +(2**23)-1, or -8388608 to 8388607 decimal.
-;; This gives six significant decimal digit accuracy.  Exponents can
-;; be anything in the range -(2**23) to +(2**23)-1.
-;;
-;; User interface:
-;; function f converts from integer to floating point
-;; function string-to-float converts from string to floating point
-;; function fint converts a floating point to integer (with truncation)
-;; function float-to-string converts from floating point to string
-;;
-;; Caveats:
-;; -  Exponents outside of the range of +/-100 or so will cause certain
-;;    functions (especially conversion routines) to take forever.
-;; -  Very little checking is done for fixed point overflow/underflow.
-;; -  No checking is done for over/underflow of the exponent
-;;    (hardly necessary when exponent can be 2**23).
