Dear Developers and All,
when I create a PDF dictionary with a small number
local mydict = lpdf.dictionary { TT = 0.000000000000000001 }
lpdf.flushobject(mydict)
I get in PDF
<< /TT 1e-18 >>
that confuses the Adobe Reader (if dictionary is used).
As far as I can investigate, lpdf.flushobject(mydict) calls
pdf.immediateobj(tostring(mydict)) and tostring does the actual damage
by introducing scientific notation.
What is the correct way to deal with the problem?
Converting the dictionary to string with my own code looks like a
possible workaround, not a solution.
Michail
PS.
Minimal example (it produces unused dictionary, so viewer does not complain)
\nopdfcompression
\starttext
\startluacode
local mydict = lpdf.dictionary { TT = 0.000000000000000001 }
lpdf.flushobject(mydict)
-- or, to the same result
-- pdf.immediateobj(tostring(mydict))
logs.reporter("","")("mydict %s",tostring(mydict))
\stopluacode
Test.
\stoptext

yes, tostring is not the most clever one on that

I'll use a different serializer. In next beta
