TypedChoiceField rejects valid input with coerce=float

[johnnybrown7@…]

django.VERSION
# >> (1, 5, 5, 'final', 0)
from django.forms.fields import TypedChoiceField
tcf = TypedChoiceField(choices=[(0.0, 'ugh'), (0.5, 'meh'), (1.0, 'yay')], coerce=float)

tcf.to_python('0.0')
# >> 0.0

tcf.to_python('0.5')
# >> 0.5

tcf.to_python('0')
# raises ValidationError('Select a valid choice. 0 is not one of the available choices.')
# same thing happens with tc.to_python('1')

float('0') works just fine, and produces a value in the choices, so why does the validation fail?

The logic around to_python and TypedChoiceField was changed in a0f3eecc in response to #21397. The behaviour you describe is no longer present.
