Why Let>I={Round(%I%)} returns invalid messages ?

Hi,

I don't understand why

Let>I={Round(50/3)}
Send>%I%

returns: 17
this is ok, but

Let>I=50/3
Let>I={Round(%I%)}
Send>%I%

returns "Invalid parameters to ROUND" and "Cannot read String as Float" messages !

Did a cut/paste from forum to my system, no typing differences.
Could not duplicate your error message on WIN XP PRO and 7.3.11.3

First formula calculated to 17.
Second formula calculated to 16.666666 and then rounded to 17.
Send> resulted in "17" for both.

Added some blank spaces to lines for more testing.
AHA!

Problem located and corrected.

Remove the extra character at the end of the
Let>I={Round(%I%)}. line

Thank you for your answer. I checked my script, but there are no blank spaces hidden.
I'm on WIN XP PRO + 7.3.11.3e evaluation.

I think this is the same bug that was fixed some versions ago, see http://www.mjtnet.com/usergroup/viewtop ... ight=round I tried it under 7.3.04 and get the same error.

Do you maybe have an older version installed ?

Happy to hear that you got the same error !
I read the link you wrote, thank you, that is exactly the information I was looking for !
Yes, I had an older version before trying the 7.3.11 eval, and I have this bug with the 2 versions. I have to try to install the 7.3.11 eval on a new system, without previous version.
Seems strange to keep this bug when an older version was installed !!

I just installed that 7.3.11.3e eval on an XP PC with 7.3.10 pro and there's no error using either version - so I think the "hangover" theory is a good one.

I FOUND THE PROBLEM !!!
In fact, there were 2 problems:

1) there is a bug in the previous versions (that's what you said Me_again)

2) I'm in France and here we write 16,666 and not 16.666 !!!

So with the 7.3.11.3e + Windows setting on . instead of , for the digits, now it works and I don't have any more the error messages "Invalid parameters to ROUND" and "Cannot read String as Float".

Thanks to you all ...

Hi,

Thanks for letting us know the solution. The complex expressions should really be able to cope with any regional numeric format and you shouldn't really have to change your settings to make it work, so I consider this a bug and will put it on the list of things to do.
