Function: type/RealRange - checks for a RealRange expression

Calling Sequence:

type(n, RealRange);

Parameters:

n - any algebraic expression

Description:

The call type(n, RealRange) checks whether n is a RealRange expression, i.e. whether n is of type function and op(n, 'RealRange'); if so, it returns true, and false otherwise.

This type is part of the `math` package and automatically initialized when this package is loaded.
