Because why not? I've populated it with some languages that I can convenient access to an interpreter for. If you post/send me .1 + .2 in any other languages, I'll try and put them up.

.3bc and dc are probably installed on your Linux or Unix box.
By the way, you should fix "Below are some examples of sending .1 + .2 to standard output in a variety of common languages." to "[...] in a variety of languages."
It also seems like the names of bc and dc are non-capitalized.
For the Haskell entry, please just shorten it to "0.1 + 0.2". The "Prelude>" thing is just a prompt for the REPL. ":m + Data.Ratio" loads the rational number module, please take the entry about Haskell's rational numbers out since yours is a page about floating point. (You might want to replace it with a comment, that Haskell supports rational numbers. But so do lots of languages in their libraries.)
C would be a good addition. (Plus Fortran, Cobol, Ada and J.)
