    4949- **^1^** Function can be easily supported on SQLite with a [https://docs.python.org/3/library/sqlite3.html#sqlite3.Connection.create_function user defined function].
    50 - **^2^** Behaviour can be emulated by using {{{SUBSTR}}}.
    51 - **^3^** Behaviour can be emulated by using {{{LENGTH}}} and {{{RPAD}}}.
    52 - **^4^** Behaviour can be emulated by directly substituting constant {{{math.pi}}}.
    53 - **^5^** Behaviour can be emulated by using {{{1 / TAN(X)}}}.
     50- **^2^** Can be emulated by using `SUBSTR`.
     51- **^3^** Can be emulated by using `LENGTH` and `RPAD`.
     52- **^4^** Can be emulated by directly substituting constant `math.pi`.
