Default "×" or "⋅"

Which do you want for the "factored post count" listing?

From the international standards (ISO.) The middle hight dot should not be used if the dot is used as the decimal separator sign (I would add or the thousands separator sign.)

In other words the x is typographically clearer.

Note that the U+22C5 DOT OPERATOR "⋅" that I pasted in my original request is different from "·" U+00B7 MIDDLE DOT, used archaically (?) as a high decimal separator. Therefore I find that U+22C5 is typographically unambiguous.

I model my request after the FactorDB: http://factordb.com/sequences.php?se...&action=last20 Note how much more clutter there would be if every multiplication was an x instead of a dot.

I propose you nick-named them as:

"x" = Donald Trump

If the final vote is 55% to 45%, then it should randomly use one choice 55% of the time and the other choice 45% of the time. Unless it's Wednesday...

I know that speaking about ISO to most people from the countries between Europe and Asia is a loss of time : they like to express the amount of energy in drachms times furlongs times fathoms divided by fortnights times jubilees :-)

The bit about typographical clarity was a quote from the excerpts of the Wikipedia articles about the relevant ISO norms.

There are a lot of different signs to represent multiplication : "x", "*", "." even no sign at all. No signa at al is not relevant here, the star is perhaps the least ambiguous, but when using pen and paper it is not as handy.

I was always taught that multiplication was a single dot in the middle of the statements (in the half-way point in the vertical plane, very clearly different than a decimal point).

I was also always taught that the audience would freak-out if they ever encountered a Sigma symbol.

Why are people freaked out about a "for loop"?

I've been taught that single dot is for scalar multiplication and cross for vector multiplication.

Yeah. I understand what you are saying. Multidimensional.

We're multilingual around here.

I believed he was referring to this:
Quote:
In British typography, the space dot is an interpunct used as the formal decimal point. Its use is advocated by laws and by academic circles such as the Cambridge University History Faculty Style Guide[2] and is mandated by some UK-based academic journals such as The Lancet.[3] When the British currency was decimalised in 1971, the official advice issued was to write decimal amounts with a raised point (for example, £21·48) and to use a decimal point "on the line" only when typesetting constraints made it unavoidable. This usage, however, has been declining since the mid-1970s, as the importation of electronic typewriters, calculators and computers from the United States and Japan familiarised Britons with using full stops and made the space dot harder to typeset.[citation needed]. The space dot may still be used frequently in handwriting, however.
By the way, even if we wind up not changing the symbol, I would still propose that a space be added between the operator and the digits, regardless of which operator we might eventually decide upon.
