This article presents my first version of my free Excel Add-In (Version 0.75 Build 151110) for calculating large numbers in Excel. The Add-In (you can download the file at the end of this article) currently implements functions for the addition, subtraction, multiplication and exponentiation of large numbers. The code in the Add-In is password protected; however you can unprotect the VBA project by using the password “excel-ticker” (without the quotes). Please also read the copyright notice and license terms in the last section of this article.
The Add-In is also digitally signed with a certificate which was issued to me by the company “TC TrustCenter GmbH, Germany”. So, only files including this digital signature have been created and published by me.
Naming conventions of the functions in the Add-In
The Add-In includes the functions described below, which can be accessed, for example, through the category “User defined” of the select function box in Excel. Each function of the Add-In is available in English, German and French.
