def conv(expr: Expression, from_base: int, to_base: int) -> Expression:
    """Converts a number from base ``from_base`` to base ``to_base`` (bases 2-36).

    Positive ``to_base`` interprets negative inputs as 64-bit two's complement
    (``conv("-1", 10, 16) == "FFFFFFFFFFFFFFFF"``); negative ``to_base`` returns
    a signed result (``conv("-1", 10, -16) == "-1"``). Trailing invalid characters
    are silently truncated (``conv("11abc", 10, 16) == "B"``). Returns NULL on
    out-of-range bases, on u64 overflow during parsing, or when a negated
    magnitude exceeds 2^63.
