[DFDL-WG] Question about unparsing with dfdl:textNumberPattern "#.##" vs. "0.##"

[Mike Beckerle]

These textNumberPatterns behave the same as far as I can tell.

I'd expect them to be different when unparsing.

When unparsing decimal number value 0.12 I'd expect....

textNumberPattern="0.##" to create a 4 character representation "0.12"

because one digit left of the decimal point is required.

But I expect...

textNumberPattern="#.##" to create a 3-character representation ".12"

because the digit to the left of the decimal point is optional and the
whole integer part is zero and so should be suppressed.

Isn't that the point of "#" versus "0" as a digit indicator in the pattern?

That's not what happens though. I get "0.12" from either textNumberPattern
pattern.

Is this a bug?
