`CDIV` blocks `FLT` and doesn't preserve base.

[python-processing-unit]

According to the specification section 9.1.3:

• INT|FLT: ADD/SUB/MUL/DIV/CDIV/POW/MOD(INT|FLT: a, INT|FLT: b) = MUST implement, respectively, addition, subtraction, multiplication, division, ceiling division, exponentiation, and remainder. Except where an operator explicitly states otherwise, a and b MUST have the same numeric type. Division by zero MUST raise a runtime error.

and the specification section 4.3.2:

Mathematical operations MUST produce results in the highest base present among numeric operands.

In the implementation, however, CDIV does not allow FLT args, and does not use the higher of it's operands base's as the base of the output.
