Documentation​

Element-wise addition. Works on numeric types or text.

Returns a column containing the result of adding other to each element of self. If other is a column, the operation is performed pairwise between corresponding elements of self and other.

Arguments​

  • other: The other column to add to this column.

Remarks​

Arithmetic Overflow​

For integer columns, the operation may yield results that will not fit into the range supported by the column. In such case, the in-memory backend will replace such results with Nothing and report a Arithmetic_Overflow warning. The behaviour in Database backends is not specified and will depend on the particular database - it may cause a hard error, the value may be truncated or wrap-around etc.
