NAME

       Rose::DB::Object::Metadata::Column::Numeric - Numeric column metadata.

SYNOPSIS

         use Rose::DB::Object::Metadata::Column::Numeric;

         $col = Rose::DB::Object::Metadata::Column::Numeric->new(...);
         $col->make_methods(...);
         ...

DESCRIPTION

       Objects of this class store and manipulate metadata for numeric columns in a database.  Column metadata
       objects store information about columns (data type, size, etc.) and are responsible for creating object
       methods that manipulate column values.

       This class inherits from Rose::DB::Object::Metadata::Column::Scalar. Inherited methods that are not
       overridden will not be documented a second time here.  See the Rose::DB::Object::Metadata::Column::Scalar
       documentation for more information.

METHOD MAP

       "get_set"
           Rose::DB::Object::MakeMethods::Generic, scalar, "interface => 'get_set', ..."

       "get"
           Rose::DB::Object::MakeMethods::Generic, scalar, "interface => 'get', ..."

       "get_set"
           Rose::DB::Object::MakeMethods::Generic, scalar, "interface => 'set', ..."

       See the Rose::DB::Object::Metadata::Column documentation for an explanation of this method map.

OBJECT METHODS

       precision [INT]
           Get or set the precision of the numeric value.  The precision is the total count of significant
           digits in the whole number. That is, the number of digits to both sides of the decimal point. For
           example, the number 23.5141 has a precision of 6.

       scale [INT]
           Get or set the scale of the numeric value.  The scale is the count of decimal digits in the
           fractional part, to the right of the decimal point.  For example, the number 23.5141 has a scale of
           4.  Integers can be considered to have a scale of zero.

       type
           Returns "numeric".
