There is decimal type (tarantool.io/en/doc/latest/dev_guide/internals/msgpack_extensions/#the-decimal-type) in tarantool.
How can I decode decimal type from tarantool response?

This patch provides decimal support for all space operations and as function return result. Decimal type was introduced in Tarantool 2.2. See more about decimal type in [1] and [2]. According to BCD encoding/decoding specification sign is encoded by letters: '0x0a', '0x0c', '0x0e', '0x0f' stands for plus, and '0x0b' and '0x0d' for minus. Tarantool always uses '0x0c' for plus and '0x0d' for minus. Implementation in Golang follows the same rule and in all test samples sign encoded by '0x0d' and '0x0c' for simplification. Because 'c' used by Tarantool.
