SQL is strictly typed, there should be no implicit conversions
between numeric types.
The only possible exception is conversion of a lossless conversion
of a numeric literal, e.g.:
float_val = 1.1 -- implicitly convert decimal constant 1.1 to float
> 4) Implicit casting is prohibited, except as described above.
