Treat integer-valued floats as their int in get_count

[eeshsaxena]

Summary

get_count(1.0) returns 2 instead of 1, so plural("cat", 1.0) incorrectly produces "cats".

The root cause is that get_count compares str(count) against pl_count_one. For a float like 1.0, str(1.0) is "1.0", which is not in pl_count_one, so it falls through to the plural count of 2.

This normalizes integer-valued floats (e.g. 1.0 -> 1) to their int form before the string comparison, so they behave like their int counterpart. Non-integer floats such as 1.5 still count as 2, matching existing behavior.

Before

>>> p.get_count(1.0)
2
>>> p.plural("cat", 1.0)
'cats'

After

>>> p.get_count(1.0)
1
>>> p.plural("cat", 1.0)
'cat'
>>> p.get_count(1.5)   # non-integer float unchanged
2

Tests

Added (1.0, 1), (2.0, 2), (1.5, 2) cases to test_count in tests/test_pwd.py. Full tests/test_pwd.py suite passes (172 passed, 16 xfailed).

Fixes #232

Hi! Gentle ping on this one; it's been open a couple of weeks. Happy to rebase or make any changes if anything's needed; whenever you get a chance to take a look, I'd really appreciate it. Thanks!
