internal usage of number's string representation
Rounding of small numbers such as 0.000020741 fail due to unexpected usage of scientific notation in internal string conversion behaviour (e.g. to 2.074100e-04).

To Reproduce
call ROUND_LREAL or ROUND_REAL with a small number (e.g. 0.000020741) and with parameter 5

Expected behavior
rounding 0.000020741 with 5 digits should return 0.00002

There are some situations where you need to communicate to third-party systems which uses hashes (e.g. MD5, SHA1, etc.) to check the integrity of sent data.

The new crypto utility would provide functions like CREATE_HASH which accepts a byte array and a hash algorithm as parameters.

First function to refactor I want DATE_TO_PARTS. It looks like there are huge misconceptions. There are FOR cycle for years and in every year 12 FOR cycles for each month. That is quite a load.

This function does not return an array, and I do not see reasons to have nested cycle. I can get rid of it completely and greatly optimize this function.
