Documentation​

Element-wise division.

Returns a column containing the result of dividing each element of self by other.

Arguments​

  • other: The value to divide self by. If other is a column, the division is performed pairwise between corresponding elements of self and other.

Examples​

Divide the elements of one column by the elements of another.​

      import Standard.Examples

      example_div = Examples.decimal_column / Examples.integer_column

Multiply each value in a column by a single value.​

      import Standard.Examples

      example_div = Examples.integer_column / 10

Errors​

  • If division by zero occurs, an Arithmetic_Error warning is attached to the result.

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.
