Description
int 
oci_field_scale ( resource statement, int field )
     Returns scale of the column with field index
     (1-based) or FALSE if there is no such field.
    
     For FLOAT columns, precision is nonzero and scale is -127.
     If precision is 0, then column is NUMBER. Else it's 
     NUMBER(precision, scale).
    
Note: 
       In PHP versions before 5.0.0 you must use ocicolumnscale() instead. 
       This name still can be used, it was left as alias of
       oci_field_scale() for downwards compatability. 
       This, however, is deprecated and not recommended.
      
     See also oci_field_precision() and
     oci_field_type().
