Is this a bug somewhere? The format function, using a specific number of digits, doesn't give sensible results:
I don't see the error. In all examples, the smallest value is 0.08953,
and it appears to be rendered to the requested number of significant
figures in each case. All the other numbers are rendered to match.
If you want to specify decimal places rather than significant digits,
you should probably use sprintf() rather than format().
