I suspect the pluralize filter is casting to an int which throws
away the fractional part. I'd clone the pluralize filter and
make a custom one that uses a "floating point
equals-within-epsilon" comparison:
EPSILON = 0.0000001 # some arbitrarily small precision
def floats_equal(f1, f2):
return abs(f1-f2) < EPSILON
register = template.Library()
@register.filter(name="oneish")
def oneish(value):
return floats_equal(1.0, float(value))
...
##### template #####
<p>This house has
{{ house.bathrooms }}
bathroom{{ house.bathrooms|oneish|pluralize }}
</p>
The above is off-the-cuff & untested, but should be fairly close
to an accurate implementation. It also abuses the fact that
"True == 1" which might be nice to make a little more explicit.
