Calling Sequence

type(expr, laurent)

Parameters

expr

expression

Description

• 

The call type(expr, laurent) returns true if expr is of type series and only contains power terms of the variable in which it was expanded.

• 

In mathematical terminology it returns true if expr is a Laurent series with finite principal part, since type series in Maple represents series with only a finite number of negative powers and with an order-term representing the truncation of a potentially infinite number of positive power terms.
