Description

If a text number parses as negative zero, ICU returns a Double which fails an assertion where we expect only infinity or NaN.

org.apache.daffodil.lib.exceptions.Abort: Invariant broken: d.isNaN().||(d.isInfinite())
[error] org.apache.daffodil.lib.exceptions.Assert$.abort(Assert.scala:143)
[error] org.apache.daffodil.runtime1.processors.parsers.ConvertTextStandardNumberParser.parse(ConvertTextStandardNumberParser.scala:235)
[error] org.apache.daffodil.runtime1.processors.parsers.Parser.parse1(Parser.scala:153)
[error] org.apache.daffodil.runtime1.processors.parsers.Parser.parse1$(Parser.scala:147), took 0.089 sec

We need to also allow the edge case where ICU returns a Double for negative zero.
