Full precision is usually excessive for debugging purposes. You'll get
silly matrices like this:
12.3243598603956866 23.397783900968423 4.39399971202043945
2.35459959006778223 3.5969699400049499 -6.2333456797887965
.....
It would be much better just to add a note to the documentation about
the precision settings...
