 The primary recommendation for number handling is to use Oracle SQL or
 PL/SQL for mathematical operations, particularly for currency
 calculations.  Alternatively you can use `fetchAsString` or
-`fetchInfo` (see next section) to fetch numbers in string format, and

-```
-ALTER SESSION SET NLS_NUMERIC_CHARACTERS = '.,'
-```
-
-Alternatively you can set the equivalent environment variable prior
-to starting Node.js:
-
-```
-export NLS_NUMERIC_CHARACTERS='.,'
-```

-Note this environment variable is not used unless the `NLS_LANG`
-environment variable is also set.
