This is running into issues with printing doubles. The default Java to-string prints doubles nicely, e.g., 3.0 and 3.14159 but sprintf (clib) can only either print 3 and 3.14159 OR 3.000000 and 3.141590. There's no "always include the decimal and at most one zero" option.

Maybe use %g?

The sticking point is that Java (optimizer) by default includes a trailing .0 for "round" floats, but %g never does. Ideally, we would include a trailing .0 so as to distinguish floats from ints when printing. (That's tracked in issue #273)
