Detailed Description

Calculator for arrays.

This class is a RPN calculator on arrays. It uses classic push/pop/operator methods. That is, push array1, push array2, add, pop arrayResult.

Author: 2007-04-01 Sean Crosby

History

2007-06-11 Jeff Anderson - Fixed bug in Push(Buffer) method. NAN was not computed properly.

2007-08-21 Steven Lambright - Moved the infix to postfix conversion into its own class.

2008-01-28 Steven Lambright - Added more support for the power operator

2008-03-28 Steven Lambright - Condensed math methods to just call PerformOperation(...). Converted valarray's to vectors (in order to use iterators).

2008-06-18 Christopher Austin - Added as well as fixed documentation

2010-02-23 Steven Lambright - Added Minimum2, Maximum2 and all min/max operations now ignore special pixels.

2010-04-08 Steven Lambright - Made min, max have proper implementations and vectors are now QVectors.

2017-08-30 Summer Stapleton - Updated documentation. References #4807.

2017-08-30 Tyler Wilson and Ian Humphrey - provided std:: namespace for isnan to fix ambiguity error when using c++11. References #4809.

2018-09-27 Kaitlyn Lee - Fixed the cout in PrintTop() so that -nan is printed as nan. Updated code up to standards. References #5520.
