RE: First calculator handling fractions
Hello!
Interesting question. In my collection I have a Casio-AL8S that can not only calculate and display fractions but also perform time and date calculations. It is from 1976 and has a vacuum fluorescent 7-digit display. Fraction display is somewhat weird as can be seen in the manual (page 9 in this document: https://usermanual.wiki/Manual/CasioAL8.71229025/view). But I am pretty certain that there must be older ones that can do fractions. Regards Max NB: To this day I have not found anything useful to do with fraction-capable calculators. We were taught fractions at school at some early stage but from then on I never encountered them again in my professional or private life. NNB: I searched the web and found this site here http://www.vintagecalculators.com/html/c...odels.html where the author claims that the Casio AL-8 and AL-10, both from 1975, were the first handheld calculators that could accept and display fractions. |
