Advanced Arithmetic HTML/Javascript Calculator

I'm looking for a skilled developer to convert an Excel calculator into HTML and Javascript. - Functionality: The calculator must be able to perform advanced arithmetic operations such as exponentiation and square roots. - Design: I prefer a minimalistic design approach for this project. - Data Retention: The calculator should not preserve user input after refreshing or closing the browser. The ideal freelancer for this job should be comfortable working with HTML, Javascript, and advanced mathematical functions. Experience in creating calculators or similar tools would be a big plus.
