Thanks Aaron for this example! I hadn't seen this before, and indeed
the suggested PR doesn't interce
@george trojan
The SciPy devs are very careful not to break backwards compatibility,
even if the changes are arguably useful. That's why the impact of the
numpy PR remains under the hood for SciPy users.
I'd love to see SciPy become more consistent with array
dimensionality, too, but that's a diff
To Andrew Nelson:

True, my bad. There is another issue with `fsolve`: it implicitly changes
the argument passed to `func`. Consider
def func(x):
# x = float(x)
if not np.isscalar(x
Presumably this also changes int(), bool(), and complex() in the same way.
The array API standard (and numpy.array_api) only requires float(),
bool(), and int() (and soon complex()) for dimension 0 arrays (the
standard does not have scalars), in part because of this NumPy issue

Hello Nico,
Any step in the direction of consistency and type safety is a good one to me.
I’m +1 on this change.
Best regards,

Responding to the post by nico.schloe...@gmail.com (I subscribe to the

I just wrote the following code:
twb = scipy.optimize.fsolve(phi, tdb, args=(tdb, p, w, hd_tdb, hg_tdb),
xtol=1e-8)
tdb, p, w, hd_tdb, hg_tdb
twb.shape
print("wet-bulb temperature {:.5f} [deg K]".format(float(twb)))
Hi everyone,
This is seeking input on PR [1] which I've worked on with @eric-wieser
and @seberg. It deprecates
```
float(x)
```
if `x` is an array of ndim > 0. (It works with all arrays of size 1
right now.) This aligns the behavior of float() on ndarrays with
float() on lists which already fails
