I agree. Reading > The invention of the decimal point led to the development of the decimal system I think the writer didn’t grasp the difference between “writing numbers as a sequence of place-valued digits, using a separator between the integer and fractional parts” and using, specifically, a dot as that separator, which (as far as we know now) came much later. The paper (https://www.sciencedirect.com/science/article/pii/S0315086024000016?via%3Dihub https://www.sciencedirect.com/science/article/pii/S031508602...) doesn’t make that error. (https://en.wikipedia.org/wiki/Decimal_separator#Hellenistic–Renaissance_eras https://en.wikipedia.org/wiki/Decimal_separator#Hellenistic–... hints at the point ‘won’ being because of the invention of thypesetting, saying “Later, a "separatrix" (i.e., a short, roughly vertical ink stroke) between the units and tenths position became the norm among Arab mathematicians (e.g. 99ˌ95), while an L-shaped or vertical bar (|) served as the separatrix in England. When this character was typeset, it was convenient to use the existing comma (99,95) or full stop (99.95) instead.”)
