There doesn't appear to be anything fundamentally wrong
with your strategy of using a regexp. There is no point
in using the s/// substitution on your string, however,
seeing as you are matching the entire string (/^...$/),
and assignment using '=', such as you have done,
is probably faster.
If you were changing only part of the string from one
format to another, you would likely be using s///, but
since you are modifying the variables mathematically,
you would have to use the s///e format, with the 'e'
for eval switch turned on. That will evaluate the
second part of the regexp, performing the math and
replacing with the result.
