> [HashCalculator converts BigDecimal and BigInteger to double to compute
> hash|https://github.com/apache/ignite-3/blob/fa79ad532b18c3a9cf277d09b4fd0e8cd25775e0/modules/core/src/main/java/org/apache/ignite/internal/util/HashCalculator.java#L152].
> Under the hood this involves weird and complicated logic - bit magic for
> BigInteger, string conversion for BigDecimal.
> This logic is too hard to replicate in non-Java clients.
> Use toByteArray() instead to compute the hash. Byte representation of those
> types is used in BinaryTuple already, so clients know how to work with that.
