allow -0 at NumberInput filling

[pamuche]

Problem

If you want to enter a negative number <1 (e.g. -0.14) <NumberInput/>-onChange automagically corrects -0 to 0 while typing. You can add the - after a not-0-number (e.g. 0.14) is filled in .

Solution

Adding special -0 input treatment in convertStringToNumber.

I can't reproduce the bug you're describing with the latest version (4.7.4):

numberinput.mov

Can you include a way to reproduce the bug, or even better, a unit test that fails in master and passes with your patch?

Yes, I was confused, that it was working in storybooks.

Here is a screencast from the poster galore demo, where it won't work:

I will check again. and look into unit testing react-admin.

The Posters Galore demo hadn't been updated in a few weeks, and the fix is recent (#8610). That explains why you had the bug there.

I've updated the Posters Galore demo, and I don't see the bug anymore.
