Hello,
look here:
-->x = 1.2345
x =
1.2345
-->msprintf("%0.1f", x)
ans =
1,2
-->string(0.1 * floor(10 * x))
ans =
1.2
This could cause disastrous results, e.g. when written to files ...
Regards
Stefan

Thank you, Leon,
it confirms that Scilab 5.4.1 handles it correctly.
But when I have LC_NUMERIC="en_DK.utf8" which means decimal comma, see
below, Scilab is in error:
-->msprintf("%0.2f", %pi)
ans =
3,14
-->msprintf("%0.2f", 3.1416)
ans =
3,14
Compare the correct handling in Python:
>>> "Pi with two decimals is %0.2f" % 3.1416
'Pi with two decimals is 3.14'
Can any of the developers comment on this, or shall I report a bug?
Regards
Stefan

Leon, Can you please try it with Scilab 5.4.1 under openSUSE? And
can you show its Bash output from
$ locale
When I was running Scilab 5.4.1 under Xubuntu 12.04, printf worked
OK, but also in Bash. So the question is: Why do you now get
different results in Scilab and Bash?
And *the important point*: Why should a mathematics program handle
inputs differently from outputs?
If one should handle decimal separators differently depending on
the local language, it should be done consistently (as in Bash,
even if I don't like it)!
One could of course have special functions or arguments to present
numbers in specific local formats.
