Speak one dollar and one cent in the singular

[SashaMIT]

What does this PR do ?

clean_numbers("$1") returned "one dollars". clean_numbers("$1.01") returned "one dollars and one cents". clean_numbers("$2.01") returned "two dollars and one cents".

The dollar plural compared the amount string to the integer 1. The amount still includes the dollar sign, so that comparison was never true. The cent plural compared the dollar string to the cent text, so one cent was plural whenever the two strings differed.

The count is now the digits in each amount. $2.02 is still "two dollars and two cents". $10 is still "ten dollars". $1,000 is still "one thousand dollars".

No existing issue.

Collection: common (text normalization)

Changelog

• Count the digits in a currency amount before choosing "dollar" or "cent".

Usage

from nemo.collections.common.parts.preprocessing.cleaners import clean_numbers

clean_numbers("$1.01")  # one dollar and one cent
