The invention of the decimal point dates back to at least 1440

In the 15th century, a Venetian merchant named Giovanni Bianchini revolutionized calculations by inventing the comma, which is used in decimal numbers. Bianchini worked for the Este family, managing their wealth and drawing up horoscopes. At that time, European astronomers used the Babylonian system of sixty, which made multiplication and other calculations challenging.

Bianchini’s innovative approach to decimals involved developing a decimal system for measuring distances and dividing units into ten equal parts. His use of the decimal point was groundbreaking for his time and even influenced later astronomers. Using decimals in calculations made the process significantly simpler than working with fractions.

Mathematics historian Glen Van Brummelen discovered Bianchini’s work while studying his treatise. The historian was amazed to learn that Bianchini’s use of the decimal point predated a German astronomer’s observation of it by 150 years. Bianchini’s trigonometric tables, which combined degrees and the 60 system with decimals, showcased his unique approach to astronomical calculations. Ultimately, Bianchini’s work demonstrated the power and simplicity of decimal numbers in mathematical calculations.

In conclusion, Giovanni Bianchini was a Venetian merchant who revolutionized calculations by inventing the comma used in decimal numbers. His innovative approach to decimals involved developing a decimal system for measuring distances and dividing units into ten equal parts. His use of the decimal point was groundbreaking for his time and even influenced later astronomers. Mathematics historian Glen Van Brummelen discovered Bianchini’s work while studying his treatise and was amazed to learn that Bianchini’s use of the decimal point predated a German astronomer’s observation of it by 150 years.
