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

Giovanni Bianchini, a Venetian merchant, revolutionized calculations in the 15th century with the invention of the comma. In 1440, Bianchini used the decimal point in his work, making astronomical calculations significantly easier. At that time, European astronomers struggled with multiplication and other calculations due to the Babylonian system of sixty.

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

A significant discovery was that Bianchini’s use of the decimal point predated a German astronomer’s observation of it by 150 years. His 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.
