A new discovery has mathematicians around the globe. Recently- documents show a decimal point in the records of a merchant named Giovanni Bianchini, who in Venice in the 1440s. Historians have the find as significant, as it the decimal point is 150 years older than was previously . Bianchini was a keen astronomer. He made many notations about his observances of the heavens. He also Venetians with horoscopes on astrological calculations of the alignment of stars and planets. Mathematician Dr Glen Van Brummelen the use of a decimal point in one of Bianchini's treatises between 1441 and 1450.

Decimal points such an integral part of life today that it seems they would have been for thousands of years. Historians say some versions of decimals have for over 1,000 years. Records show a form of the mathematical dot used in the Islamic world in the 900s. It is likely that Bianchini travelled to the Middle East and was by scholars there who were key in many mathematical concepts. Other historical evidence intellectuals using a form of the point in China in the 1200s. Before the recent discovery, the earliest definitive use of the decimal point in 1593.
