First code sample from docs has several errors

First code sample from https://numbakit-ode.readthedocs.io/en/latest/#numbakit-ode-leveraging-numba-to-speed-up-ode-integration:

>>> import nbkode
>>> def func(t, y):
...     return -0.1. * y
>>> t0 = 0.
>>> y0 = 1.
>>> solver = nbkode.Euler(func, t0, y0)
>>> ts, ys = solver.run([0., 5., 10.])

Has a trailing . in -0.1. * y:

In [1]: >>> import nbkode
   ...: >>> def func(t, y):
   ...: ...     return -0.1. * y
   ...: >>> t0 = 0.
   ...: >>> y0 = 1.
   ...: >>> solver = nbkode.Euler(func, t0, y0)
   ...: >>> ts, ys = solver.run([0., 5., 10.])
  File "<ipython-input-1-45132754029e>", line 3
    return -0.1. * y
                 ^
SyntaxError: invalid syntax

But even after removing it, it fails:
