Math Editor decimal points

[Michael]

The recently released version of i2 Pro (1.1.5.0085) still has the problem that decimal points in non english languages are not read correctly. My computer is in german. When I type formulas I need to use a point "." as a decimal separator. In the constants editor I must use a comma "," as a point is ignored. But then the interpretation is not done correctly. I2 does not read the value after the comma. Example:

The results of

Code: Select all

channel * 1.5

and

Code: Select all

channel * CONSTANT

whereas "CONSTANT is 1,5" are not the same.

The result of

Code: Select all

channel * CONSTANT

is equal to

Code: Select all

channel * 1.0

Besides that it is not very intuitive to use two different decimal separators in the channel editor and the constants editor!

The recently release Beta (i2 Pro V1.1.5.0127 Beta) still has the same problem. Will this be fixed sometime?

Hi Michael,

Unfortunately in this particular instance of the language decimal separator issue will not be fixed, as it is embedded in the math engine itself.

Unlike other instances like PDM where due to the script being auto populated apart from the channel values themselves in i2, the script is looking for specific symbols for the expressions and therefore cannot be changed without rewriting the entire maths script for i2.

This may change down the line, but at this stage, the only way maths can function is with a period for the decimal separator and commas used for the end of expressions.

Hi Nathan,

thanks for your update. Are you aware that with not fixing this issue, i2 is not useable anymore on computers that use a comma as a decimal separator (most european languages)! The calculations are simply not correct if you want to use constants because the "," is not used correctly. I don't really understand why you don't simply change it back to use "." again like in previous versions.

Hi Michael,

I will start off with my sincerest apologies on this. In my initial inability to reproduce the issue and discussion with one of the software engineers I missed the specificity of the problem you were experiencing.

After your email to Gareth, and some further testing from him I have now been able to understand reproduce the problem for myself and for the software team.

This issue will be investigated and fixed before .127 becomes a release.

I was able to work around the issue and get a "." to be accepted and entered in the constants by changing the keyboard setting to an english keyboard.

I understand this is not an ideal solution, and has other complications, but it is the only workaround I have to offer at this stage until a fix is implemented. You can Switch between keyboard layouts relatively quickly using the 'windows' + 'space bar' keys provided you have the additional keyboards available.

Hi Nathan,

thanks for the info! I can confirm that changing to an english keyboard layout is working! That's already something.
