Ralf Handl commented on OLINGO-1087:
------------------------------------
The default of 0 was specified in OData V2:
2.2.1.7 Decimal
The Decimal type represents numeric values with fixed precision and scale. The
required precision and scale can be specified using its optional Precision and
Scale facets. This type can describe a numeric value ranging from negative
10^255 + 1 to positive 10^255 -1.
2.2.1.7.1 Facets
2.2.1.7.1.1 Precision
This is a positive integer that specifies the maximum number of decimal digits
that an instance of the decimal type can have, both to the left and to the
right of the decimal point. Possible values for Precision are 1, 2, or 3.
2.2.1.7.1.2 Scale
This is a positive integer that specifies the maximum number of decimal digits
to the right of the decimal point that an instance of this type can have. The
Scale value can range from 0 through the specified Precision value. The default
Scale is 0.

> The "precision" found in a read number is currently at least the number of
> decimals (omitting trailing zeroes). That seems to be wrong, or at least not
> consistent with at least some server side view of the matter, for numbers
> smaller than 0.1 (the number shown has 35 decimals, but precision 34):
