In terms of input range, I've gone for -999999999.999999999 to
+999999999.999999999. This should be sufficient for a wide range of
purposes (for example, if you convert a dimen into a floating point
number in units pt then you are safe for any dimen TeX can handle).

Please would you clarify for me, Joseph.  Does this package provide floating point numbers, as described in:
    http://en.wikipedia.org/wiki/Floating_point

From what you've written above it seems that your implementing fixed point.
    http://en.wikipedia.org/wiki/Fixed-point_arithmetic
namely "a fixed number of digits after (and sometimes also before) the radix point".
