\brief Concrete type class for 256-bit decimal data Arrow decimals are fixed-point decimal numbers encoded as a scaled integer. The precision is the number of significant digits that the decimal type can represent; the scale is the number of digits after the decimal point (note the scale can be negative). Decimal256Type has a maximum precision of 76 significant digits. (also available as Decimal256Type::kMaxPrecision). For most use cases, the maximum precision offered by Decimal128Type is sufficient, and it will result in a more compact and more efficient encoding.
