Number (Oracle Fusion Middleware Java API Reference for Oracle ADF Model)

This class extends oracle.sql.NUMBER, Oracle's Java representation of the NUMBER database type. This class allows an instance of the oracle.sql.NUMBER to be used as a domain object. The intent of many of the methods in this class is to wrap the corresponding method in the oracle.sql.NUMBER class such that it returns an instance of an oracle.jbo.domain.Number object.

The oracle.jbo.domain.Number domain class is the Java representation of the underlying database type that you must use if you want to exploit the domain feature of Business Components for Java.

                                           int scalelen,
                                           java.lang.String lang)

Converts a string to a number with specified precision.

Parameters:: num - a string representing a numeric value.; precflag - a flag indicating that precision restriction should be applied.; preclen - the maximum number of the decimal digits the result may have, subject to the scale requirement. This argument is ignored if precflag is false. If the number of digits would otherwise exceed preclen the number will be rounded.; scaleflag - a flag indicating that the scale restriction should be applied.; scalelen - the maximum number of decimal places allowed to the right of the decimal point. Negative values are allowed. This argument is ignored if scaleflag is false. This argument takes precedence over preclen. If precision is specified but scale is not, the scale is assumed to be 0.; lang - the NLS language the conversion is to be performed in. If null the default language is used.
Returns:: a new Number object.
