Journal on Software Engineering 2230–7168 11 3 19 30 Scientific Calculator, Case Structure, Enum, Numeric Constant, Numeric Control and Numeric Indicator Icons, Functions, Case Structure, Formula Node, LabVIEW The main objective of this paper is to simulate scientific calculator using NI LabVIEW software, a graphical programming language to automate the calculation procedure making less paper work for problem solving. In this work, the authors build logics by wiring icons in block diagram which is a graphical source code instead of line of text and the front panel acts as a user interface of the VI to create fully featured scientific calculator. It enables execution highlighting on block diagram and makes the flow of data visible at run-time engine and real-time operating system. This software enables the user to correct the errors with an indication of broken arrow (Run button) on the pull down menu. January - March 2017 Copyright © 2017 i-manager publications.
