The letters between Giovanni Bianchini and Regiomontanus in 1463–1464 mention works by Bianchini entitled: Primum mobile (astronomical tables included), Flores almagesti, Compositio instrumenti.
Bianchini is the first mathematician in Europe to use decimal positional fractions for his trigonometric tables, at the same time as Al-Kashi in Samarkand.
In De arithmetica, part of the Flores almagesti, he uses operations with negative numbers and expresses the Law of Signs.
