I have recently faced a problem, where I had a bunch of SVG files with a
large amount of fraction numbers in the path definitions. These images were
displayed in small size, so this amount of precision was irrelevant, and
these numbers took almost half of my SVG images’ size. So I created an
Elisp defun to round these numbers to 2 decimals:
This finds the first digit of the number under point (the cursor), and
reduces its digits to the given amount (or the number given with C-u). It
has some drawbacks, though, as it cannot handle exponential forms (e.g.
1e-1234), but these were rare in my case, and its hard to iterate through
all numbers. I will come over this latter problem soon(ish).

also a freelancer self- and software developer.
He is learning about different IT subjects since the late
1990s. These include web development, application building,
systems engineering, IT security and many others. He also dug his
nose deeply into free software, dealing with different types of
Linux and its applications,
while also writing and contributing to some open source projects.
On this site he is writing posts about different stuff he faces
during work (oh my, yet another IT solutions blog), hoping they
can help others with their job, or just to get along with their
brand new netbook that shipped with Linux.
