Precision Issue in "int DiGSDFunction::calculateGSDF()"

[ghost]

When I use function "int DiGSDFunction::calculateGSDF()" to calculate the GSDF Values, I found the result is different from the value in DICOM Standard document(PS 3.14 - 2008 Page 21 Table B-1)

for example: JND 1023 in Standard the Lum is 3993.4040 but in dcmtk calculate result is 3993.3296, why?

I guess that the table in the DICOM standard has been calculated with a higher (?) or at least with a different precision than what calculateGSDF() does. But I don't think that this is really an issue ...

Btw, the table in Annex B is only informative (and not normative).

Thank you for your reply. I agree with you.
