 * NAME
 *   27. dataTypeNumber2.js
 *
 * DESCRIPTION
 *    Testing Oracle data type support - NUMBER(p, s).
 *
 * NUMBERING RULE
 *   Test numbers follow this numbering rule:
 *     1  - 20  are reserved for basic functional tests
 *     21 - 50  are reserved for data type supporting tests
 *     51 -     are for other tests
