math: formula alignment: confusion about `left` and `right` alignment

Dear ConTeXt folks,


looking at the Wiki page about changing the formula alignment [1] and
testing the following minimal example, which is also attached, I would
have thought that `align=right` would mean, that the formula is put to
the right side. But is aligned to the left side instead.

--- 8< --- minimal example --- >8 ---
\starttext

Right align.
\setupformulas[align=right]
\startformula
ℕ ⊂ ℝ
\stopformula

Left align.
\setupformulas[align=left]
\startformula
ℝ ⊂ ℂ
\stopformula
\stoptext
--- 8< --- minimal example --- >8 ---

What is wrong with the way I am looking at this?

Searching for »latex align formula left right« I could not find an
answer either.


Thanks,

Paul

Nothing; the reasons are historical. When defining "left" and "right", the author thought of "raggedleft" (the text is ragged on the left) instead of "flushleft".

To avoid confusion, you may want to use "flushleft" and "flushright" explicitly.
