This seems to be an entirely silly thread which has essentially nothing to do with prime numbers. However, it's Friday afternoon here in the UK, and that's traditionally a time (again, in the UK) for mild silliness. So, for what it's worth, I've always used the convention where a baseline dot represents a decimal point or a full stop ("period" in the US) and the centred ("centered" in the US) dot for a multiplication symbol. As far as I am aware, this convention is widespread in the UK.

As for money, we also use a baseline dot these days. £1.50 is about \$2.49 at the moment or, to remove ambiguity, GBP 1.50 is close to USD 2.49. Back in the good old days, we would write GBP 1.50 as £1/10/0 but that went out of fashion a little over 32 years ago.

ObPrime: 183, the number typed on some Windows systems to get a centred dot, is prime.

In order to complete the vision, in Spain actually coexist, in a chaotic
situation, the traditional base-line comma and the base-line point, while
middle point · ([Shift]-[3] in my keyboard, Alt-183 is À, a capital A with
french grave? accent) is often used for multiplication.

But in my primmary school (a lot of years ago), I learned to use upper
comma, writing 2'3 = 23/10 or 3'14 = pi. It is totally old fashioned, but it
was totally unambigous ...
