Use the Numeric Parameter window to specify a numeric tolerance for your transformation. A numeric tolerance is a number that you apply to numeric find values. The numeric tolerance allows the replacement of a value that is just outside a find value or a range of find values.
For example, you use the Discretize clean type to replace the find value numeric ranges in the following manner:
23.50 -24.50 replaced by 1000
If you specify a tolerance of 0.10, then input data of 23.40 and 24.60 would also be replaced by 1000 in the example above.
The default value is 0.0.
To specify a numeric tolerance for your Clean Data transformer:
In the Numeric tolerance field, type a numeric tolerance.
Optional: If you do not want the Clean Data transformer to copy a value if it matches a column in the rule table, select the Do not copy record to output if rule match is found check box.
