---------------------------------------
Summary: dfdl:textNumberFormat "#.##" unparses 0.12 as "0.12" but
should be ".12"
Key: DAFFODIL-2859
URL: https://issues.apache.org/jira/browse/DAFFODIL-2859
Project: Daffodil
Issue Type: Bug
Components: ICU
Affects Versions: 3.5.0
Reporter: Mike Beckerle
Due to ICU bug
[https://unicode-org.atlassian.net/browse/ICU-22558]
dfdl:textNumberPattern strings with # only, and no digits before the decimal
point still end up creating a 0 digit before the decimal point.
For example "#.##" should format 0.12 as ".12" without a leading zero.
This could be worked around in daffodil code by detecting when to call the
`DecimalFormat.setMinimumIntegerDigits(0)` on the number format object.
This requires a minor analysis of the ICU number pattern.
