Built-in functions for bitwise operations
Since Cosmos DB doesn't support bitwise operations on 64-bit numbers (due to lack of support of it in JS), it would be great to have built-in functions like AND, OR, XOR.
Bitwise operations are widely used e.g. in the calculation of Hamming Distance, one of the most used distance metrics in Machine Learning.
Work on this feature has started. Will update here when complete.
