The following module was proposed for inclusion in the Module List:
modid: Units::Calc
DSLIP: bdpfp
description: Human-readable unit-aware calculator
userid: SFINK (Steve A Fink)
chapterid: 6 (Data_Type_Utilities)
communities:
similar:
Math::Units Convert::Units
rationale:
Not sure where to put this in the hierarchy. This is a unit-aware
desktop calculation module that attempts to figure out reasonable
units to display values in. Example output (ucalc is a thin
command-line wrapper for the module):
% ./ucalc "8KB / (8KB/(20MB/sec) + 15ms)" 532.3 byte / millisec
1.785 gigabyte / hour 42.83 gigabyte / day 519.8 kilobyte / sec
30.46 megabyte / minute (That calculation is an 8KB random I/O
throughput estimate based on 20MB/sec sequential transfers and 15ms
average access time.)
This is similar to Math::Units in that it involves unit conversions
(though Math::Units is much more complete), and to Convert::Units in
making some attempt at dealing with human-readable unit descriptions
(Convert::Units goes much farther in that direction, since that is
its primary focus). Neither of them tries out different possible
outputs. Which, incidentally, was the reason why I couldn't really
use either of them as a subroutine, though I'd like to add a way to
plug them in with restricted functionality.
It doesn't make sense to me to put it under Convert::, since
conversion isn't the focus of its functionality. Math:: makes more
sense, but calling it Math::Units::Calc implies a nonexistent
relationship to Math::Units, and I'm not sure where else to put it
in there. Math::Calc::Units?Suggestions appreciated.
