$.$ should be used to separate the decimal part of a number from the integral part, not a comma ,
$,$ as is common in some languages. This is because commas are already reserved for separating mathematical notation such as arguments of multivariate functions, elements of a set, and the coordinates of ordered tuples.
It is preferable to write scientific or engineering notation like this: $4.15 \times10^{n}$. The $\mathcal{MathJax}$ markdown for our example is 4.15\times10^{n}
$4.15 \times10^{n}$. It is recommend that you not precede or followThe spacing around \times
with positive nor negative spaces because \times
takes$\times$ is taken care of spacing on its own, so there is no need to insert the spacing manually.
