* Add type coercion and null check to left, right, repeat exprs. These exprs shouldn't validate types; they should coerce types. Coercion is typical behavior for functions because it enables schema evolution. The functions are also modified to check isNumericNull on the right-hand argument. This was missing previously, which would erroneously cause nulls to be treated as zeroes. * Fix tests. |
