Follow-up Comment #7, bug #44245 (project octave):

Oh bother Matlab!

> We could have a warning about these formats when converting non-integer
values. I suppose it should be disabled by the --traditional option.

If you can do that I think that is the best way to support this.  It's unclear
how much code relies on the current Octave implementation, but at least the
warning would flush it out.

I will take a look at the 1367 instances of printf in core and fix them.

What does Matlab do with the string format specification and a double value? 
Does it also print out using '%g'?

sprintf ('%s\n', 15.2)
