Maybe it will turn out that way.

For the time being, there are at least two sets in common use:
  1. Decimal point, multiplication ×, division ÷
  2. Decimal comma, multiplication •, division :
And there are internationally agreed fixed symbols (hurrah!!) for additions, subtractions, for dot (scalar) products and cross products.

Maybe we should use a third set for the two common arithmetic operations: multiplication * and division / ? It's quite spread in programming languages ...
And it's clearly visually differentiable - another advantage. Just compare:
  1. 1.2 + - × ÷ • ×
  2. 1,2 + - • : • ×
  3. + - * / • ×
