\ cora_4.0.fs -- Coraphyco COnversion RAtios and PHYsical COnstants
\ Version 4.0
\ 2011/6/14 David Meyer <papa@freeshell.org>
\ Coraphyco provides a Forth environment to facilitate conversion of
\ quantities among a large variety of measurement units and systems.
\ Inspired by Frink by Allan Eliasen.
\ Changes in version 4.0
\ - Convert to integer arithmetic from floating-point for
\ portability and usability.
\ - Rewrite user interface to present unique word for each
\ conversion instead of unit-to-base constants and generic
\ conversion word ->.
\ Notes:
\ - On Zaurus, one cell is four bytes, therefore max. single-
\ precision integer is $ffffffff = 4294967295 (unsigned) or
\ $7fffffff = 2147483647 (signed)
\ - NetBSD (SDF) compilation uses eight-byte cells. Max. single-
\ precision integer: $ffffffffffffffff = 18446744073709551615
\ (unsigned), $7fffffffffffffff = 9223372036854775807 (signed)
\ - Largest conversion ratio: parsec:mm (30856775813057300000.)
\ (requires double-precision for integer arith., even on SDF)
