    Common logarithm

    The Common logarithm step computes the common logarithm of the input values (log10(x) or sometimes also log(x)). Common is a logarithm with base equal to 10.

    Parameters

    • Input column: a numeric column (decimal or integer).

    • Target column: configure the column which will receive the output. Output will always be of decimal type.

      • Write result to the current column: overwrite the input column with the result.

      • Create new column with name: create a new column with specified name. Name of the new column can contain spaces or special characters - technical column name will be created automatically. The new column will be placed right after the input column.
