org.apache.arrow.flatbuf.Decimal
public final class Decimal extends com.google.flatbuffers.Table
Exact decimal value represented as an integer value in two's complement. Currently only 128-bit (16-byte) and 256-bit (32-byte) integers are used. The representation uses the endianness indicated in the Schema.
