Just setting ->decimal isn't correct; that signifies that ->sig stores the number in decimal128 format (host-endian DPD), so it's only correct for a REAL_VALUE_TYPE that actually is encoded in decimal128 format, not one copied from dconst*. I think build_real is a reasonable place to handle the dconst* special cases, but it would need to have an explicit mapping from the binary dconst* to corresponding constants using the decimal128 format, in the case where the REAL_VALUE_TYPE passed in is binary but the requested type is decimal. -- Joseph S.
