I have following decimal in a template:

(decimal name=“MDEntryPx” id=“270” presence=“optional”)
(exponent)
(/exponent)
(mantissa)
(delta /)
(/mantissa)
(/decimal)

if MDEntryPx= 35 which of following encode is correct?

  1. exponent = 0 mantissa = 35
  2. exponent = 1 mantissa = 35 (because MDEntryPx optional)

Douglas,

alternative 2 is correct.

exponent=0 represents a NULL value (in which case no mantissa follows)
exponent=1 represents a zero value

(with delta coding, mantissa=35 is correct given that it is the first occurrence or the previous mantissa value is 0 (zero))
