We trace Clavius's use of decimal fractional numeration and the decimal point back to the work of Giovanni Bianchini (1440s), whose decimal system was a distinguishing feature of his calculations in spherical astronomy and metrology. While one needed to operate with Bianchini's decimal system to work with his astronomy, Regiomontanus copied it only in part. The rest of the European astronomical community followed Regiomontanus, and Bianchini's system reappeared only with its revival by Clavius.</p><p>La première apparition connue du point décimal se trouve dans la colonne d'interpolation d'une table de sinus dans l’<em>Astrolabium</em> de Christopher <span>Clavius (1593)</span>.
