In my answer to this question (Simpler input for the new unit support), I am trying to show that two different lines of code give the same result (490. m). I thus entered the following text:
However, I instead got this, in which my second entry of "490. m" is displayed as "491. m":
I tried deleting the second instance of "490. m" and reentering it, to no avail—the system still displays "491. m".
I get the same result when I add a right-arrow before the second "490. m", as follows:
However, when I instead write "490 m" (without the period), the anomalous behavior disappears. But then, to display the results on separate lines, I have to put an additional hard return between the two, and put a right arrow before each.
[N.B.: If you go to to my answer, you won't see the "491. m"; I deleted it to avoid the confusion it would cause.]
