Comma as decimal point

Postby Karunen » Tue Sep 02, 2014 1:29 pm

Hi all,

If you are using a operating system with a language that uses a comma “,” as a decimal point “.” (French, German, Swedish, Italian, etc.),
then you will find that then using maths channels with decimal points you will have some issues.

This is because the software uses the operating system to break the numbers but it also use comma to separate variables when using function such as the high pass filter.

Maths Channel Wizard (High Pass filter Example)

Unfortunately as this requires a major rewrite for the maths channel it may take a while before we are able to fix this issue.

While we are currently looking at this issue you can work around it by changing the decimal symbol of your language settings

Please go to Start > Control Panel > ...

Windows XP : Regional and Language Options>Customise

Windows Vista : Languages and Region > Customise this format.

Windows 7 : Region and Language > Additional settings

Windows 8 : Language> Change date, time or number formats > Additional Settings

And changing the Decimal symbol from a comma to a full stop.

Please accept my apologises for any inconvenience this may cause.

Kind Regards,

Windows Regional settings are now supported in PicoScope 6.11.10. :)

So for most European languages ie French, German etc
You can now use a comma symbol ',' for the decimal place and a semicolon symbol ';' for the list separator, in maths channels.

An other issue is the export of a serial decoded list into a csv-file. With a German windows-installation you get commas as separator and also a comma as "decimal point". So all my first exports are unusable, because all numbers with a comma as decimal point are separated into two rows. For example a -0.321 is stored in the csv-file as -0,321 and will be stored in a spreadsheet as RowA -0 and RowB 321.

It would be very useful if the character to separate the rows could be selected.

best regards,

The development team are aware of this issue, and are currently looking at the language support options.
