Heavy Duty Calculator

General Purpose Windows Calculator

Estimated Release: October 2021


-        Calculations on the whole screen

-        Fractions

-        Repetitive parts

-        Feedback on lengthy calculations


The Heavy Duty Calculator adds extra value compared to other calculators, without adding complexity. This is done by dropping some implicit assumptions, like all numbers should fit in 64 bit. And no use of a single line display, as you have a whole screen at your disposal. And as the 64-bit border is dropped, lengthy numbers come into play and so are the calculations of repetitive parts.

Design Principle to ease the burden of communication between systems

The Global Design Pattern is an example of a 'simple solution for a complex problem'. In the current message broker architecture, you need to build an infrastructure containing exchanges, queues, consumers and producers. With the Globals Design Pattern, you only have your data to care about, while the supporting infrastructure for sending and receiving it is abstracted away. A simple declaration & assignment is enough to send data, Implementing a simple handler is enough to receive data.
