Hello,
After having worked with Perl quite a bit and written lots of modules
over the past 2 years for personal use, I think some of the work is
ready for sharing with the Perl community. I am an electrical engineer
and mainly use Perl for writing (parts of) CAD tools, so my focus
is on mathematical issues and processing of text files in an unspecified
number of formats.
I have already shared much code with my colleagues (I estimate about 40
use it, with about 10 amongst them being aware of it). I have already
posted a specific request about releasing modules for handling files
written in a format named Spice. Although this is a very popular format
in the field of analog circuit simulation, I got no response. But I
think interest in this and other modules could arise any moment. There
are some freeware projects around for writing circuit simulators, and
their analog parts may benefit from such code. I must admit, though,
that all this is still hypothetical.
Anyway, I hope this low response does not keep you from letting me share
my efforts. I have reaped many benefits (not financially ;-) from using
modules available at CPAN, and think I have the needed experience and
discipline to give the people something useful instead of letting them
work out a mess.

To start with, I would submit Number::Spice, a relatively small module
for converting to and from a special number format with literal suffices,
which is allowed by the spice simulator. DSLI entry:
Number::Spice adpf Conversion of Spice numbers WIMV
Attached you will find a README file for the Number::Spice module.
Hope to hear from you soon!

Number::Spice groups functions for converting plain decimal numbers to/from
the shortened Spice syntax.
Spice syntax provides a shortcut for writing down numbers in scientific
notation, by appending a suffix to the value which corresponds to a
numeric multiplier. The following table lists the minimal suffices and
the corresponding multiplier:
T 1.0E12
G 1.0E9
MEG 1.0E6
X 1.0E6
K 1.0E3
M 1.0E-3
MIL 2.54E-5 (i.e. 1/1000 inch)
U 1.0E-6
N 1.0E-9
P 1.0E-12
F 1.0E-15
A 1.0E-18
Following functions are available:
pattern returns a regular expression matching a spice number
is_spice_number returns true when the given string is a clean spice
number
split_spice_number returns the parts in a spice number (string)
suffix_value returns the numeric multiplier corresponding to a
suffix
spice_to_number converts a spice number (string) to a float
number_to_spice converts a float to the shortest spice number (string)
normalize_spice_number converts a spice number (string) to its shortest
equivalent
The following scalars are available for exporting:
$RE_NUMBER regular expression matching a float
$RE_SPICE_SUFFIX regular expression matching a spice suffix
$RE_SPICE_NUMBER regular expression matching a spice number
