I did of course wrap the c-implemented sparse matrix as a Ruby object, but that can handle only doubles (which is nice most of the time) and needs a c compiler and ruby sources etc to be installed. For portability reasons, it would be nice to have a pure Ruby implementation.

The columns store the actual values (doubles), and the rows store pointers to the corresponding doubles. This way, I can update a double directly via the columns, via the rows after dereferencing the pointers.

Initial Comment:
ruby --version
ruby 1.8.4 (2005-12-24) [i686-linux]
irb --version
irb 0.9.5(05/04/13)

I did the following:

=> Infinity

I would expect s.to_i.to_f to yield exactly the same result as s.to_f, because the string contains far more digits than are significant for Float, so the digits after the decimal point are discarded anyway.
