Excerpt

Formats a numeric set of values according to the specified number formatting. Source values can be a literal value, a function returning a numeric value, or reference to a column containing Integer or Decimal values.

  • If the source value does not include a valid input for this function, a missing value is returned.
  • When a NUMFORMAT transform  transform is applied, the column can be re-typed to a different data type. For example, if your format string (second parameter) is is '#' (a single hash mark), then all values are rounded to the nearest integer, and the column is re-typed as Integer.

    Tip

    Tip: In general, you should format your numeric data after you have completed your computations on it. In some cases, you might lose numeric precision in converting formats, or your data can be re-typed to a different data type (e.g. Decimal to Integer).

  • For more information on formatting date values, see see DATEFORMAT Function.
