\brief Concrete type class for 128-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). As an example, Decimal128Type(7, 3) can exactly represent the numbers 1234.567 and -1234.567 (encoded internally as the 128-bit integers 1234567 and -1234567, respectively), but neither 12345.67 nor 123.4567. Decimal128Type has a maximum precision of 38 significant digits (also available as Decimal128Type::kMaxPrecision). If higher precision is needed, consider using Decimal256Type.
