Fixed Currency to only Display Cents When Needed

[cheng-jess]

Fixes #554 by updating base.py

Changes proposed in this pull request:

• Updated to_currency() in base.py to only display cents when input has a decimal (or explicit cents)
• e.g. 100 -> one hundred euro, 100.00 -> one hundred euro, zero cents
• Changed tests to align with this fix

Status

• READY
• [] HOLD
• [] WIP (Work-In-Progress)

How to verify this change

• Run all tests in /tests
• Try "num2words 100 -t currency" and "num2words 100.00 -t currency" in the command line

Additional notes

Not sure if this issue was a wanted bug fix or feature, but updated base.py to stop cents from being converted to words when not explicitly included in the number input (e.g. handling 100 vs 100.00 differently).

Hello @cheng-jess , thanks for contributing
This PR appear to run on a loop on the test and never ends, can you review to make sure its ok ?

@mrodriguezg1991 It looks like this is failing due to the Amharic cardinal test cases (28-33 in test_am.py)--these don't appear to be related to the cents issue.

@cheng-jess what's the purpose of these test cases?

I am also interested in getting this issue resolved. 🙂

[bryananderson]

Oh it looks like it's related to @cheng-jess 's other PR here, probably these cases were meant to go there.

I opened a new PR here which removes the erroneous test cases.
