O - order term

Calling sequence:
O(expr)

Parameter:

expr   --  expression

Summary:

O gives the order term of a series expansion. The argument of the order term
has to be a polynomial. It is defined by the expression expr.

The arithmetical operations +, -, * and ^ are defined for ordinal terms. When
calculating with ordinal terms it is assumed that the limit value is finite, i.e.
an expansion "at infinity\ cannot be represented by O.
