[Feature Request] Add an option to remove unnecessary characters when writing to a file

[mpage21]

I would really appreciate a parameter for writing to files that would strip off unnecessary characters to save space. For example:

0.0 --> 0
5.0 --> 5
0.034 --> .034

In files like mine where I have a matrix with a bunch of 0.0's this would save a significant amount of space, without losing any information.
