When you edit flat file definitions, you can define formats for numeric values with the Number datatype. Bigint, double, and integer datatypes have a default precision, scale, and format. You can change the precision for a column that is an integer or double datatype.
Use the Format column on the Columns tab of a flat file source or target definition to define the format for numeric values.
You can define the following formatting options for numeric values in the Column Format Settings dialog box:
Numeric data
Field width
When you define formatting options in the Column Format Settings dialog box, the Designer shows the options you define in the Format column on the Columns tab.
