I thought this reference might be interesting.

(Cajori was often cited as an author, afaik, in

pre-Internet days)

Europe would show [decimal 1/4] as [0,25] ; the USA, as [0.25].

I understand that India subdivided large integers into groups of four, but I

think we've discussed that briefly, already.

Topic for another time: Mathematical notation is often akin to slang!

A book by Florian Cajori (A History of Mathematical Notations, Dover Books,

ISBN 0486677664) gives a detailed history of how and where the different

notations more or less 'settled'. The book is a bit dated, but the confusion

has been reduced a little since its publication. The number of different

separators that he mentions in use in the 19th and early 20th century are

quite a few. Up to eight variations of decimal notation are mentioned by

Cajory as 'in use within the last 35 years'.

Crocuses to all!

(Crocuses are the very first plants I see in the spring.

I just *adore* them.) I should be able to provide some photos,

taken a year ago.

...gotta start my Web site; none yet.

Crocuses have coming up!

I detest arrogance.
