I just remembered you'll need this beauty in order to run

I like to use IDL to make nicely formatted tables or listings of data to drop into, say, latex or other software. One of my pet peeves in IDL is that the numbers always give a large number of digits, and there are leading spaces. So, a while back I wrote to take care of this. It's very handy!

e.g. if x = 5.43961

print, trim(x,2) yields 5.44 (it rounds, rather than truncates)

you can find it here.
