Semantic type with Decimal encoding for a field which is not a Price, Qty, Amt or Percentage about fix-simple-binary-encoding HOT 4 CLOSED

In FIX, the base type of Price, Qty, Amt and Percentage is called "float". It may be used as a semantic type if it doesn't fit those specific categories.

(The FIX Repository contains the datatype taxonomy and mapping to other standards. Float and its subtypes all map to xs:decimal in FIXML.)

I have been using Float in these cases, but the RC4 documentation doesn't allow for a Float to be presented as decimal encoding:
https://github.com/FIXTradingCommunity/fix-simple-binary-encoding/blob/master/v1-0-RC4/doc/02FieldEncoding.md

Could the documentation be updated to allow for it?

I see your point. There is confusion between FIX semantic type float and IEEE floating point primitive. The FIX semantic type system doesn't properly distinguish between floating point and fixed point numbers or between binary and exact decimal numbers.

Discussed on June 21 call.

There are issues with the FIX datatype taxonomy. The float type is used represent ratios, rates, price increments and more. This should be clarified.

Nevertheless, semanticType attribute is metadata for the application layer. SBE implementations should not restrict wire format based on semantic type.
