<font face="Courier New">Dear all,<br>
<br>
I think a half-high (centered) dot "·" is a better (and more
standard) multiplication sign, it does not take much space and
it cannot be confused with the decimal separator ".", for
instance <br>
<br>
1 + Ts·s - A·s</font><font face="Courier New"><sup>2</sup></font><font
face="Courier New"> <br>
<br>
</font>1 + 2.·s - 0.27·s<sup>2</sup><br>
<br>
However, I think the decimal dot shouldn't be used in a block
diagram, its only use is to indicate they are real numbers, but
block diagrams never refer to integers so the decimal dot is
somewhat pedantic.<br>

<p>?<br>
When a decimal number is integer, the dot is not displayed. With
your dot, it would give<br>
1 + 2·s - 0.27·s<sup>2</sup><br>
So the confusion could be only with cases like 1 + 2.55.s<br>
<br>
I was told that in formulae, the most standard is to use space
between multiplied symbols.<br>
This is what looks the most widely used. Please see for example<br>
