<p>
The range_error class  is derived from the  runtime_error class.
The range_error class represents exceptions  that are  occur because
some piece of the software component that causes the exception is attempting
to work with a value that is either to large or to small to represent in
the current environment.  The value is a legitimate value but beyond the
representation capabilities of the current machine.  This is in contrast
to the out_of_range exception which represents values that are not legitimate
for operation they are involved in.  This class represents
a node class and  can therefore be used as a base class for user defined classes.

<h3>Description</h3>
<p>

A set possible solutions is sometimes supplied with the exception description in addition
to the type of error.
