#precision ⇒ Object

The precision of numeric type attributes. If the precision is nonzero and scale is -127, then it is a FLOAT, else it is a NUMBER(precision, scale). For the case when precision is 0, NUMBER(precision, scale) can be represented simply as NUMBER.

#scale ⇒ Object

The scale of numeric type attributes. If the precision is nonzero and scale is -127, then it is a FLOAT, else it is a NUMBER(precision, scale). For the case when precision is 0, NUMBER(precision, scale) can be represented simply as NUMBER.
