Value in trend is coming in exponent
In one project, we have connected the totalizer value in Trend Acquisition block.
The values in trend window was coming fine till 99999.0 but as the toatalizer reading crossed this value, the value in trend window is coming as exponent.
Kindly tell what is the reason behind this and how this can be resolved. is there any setting problem in Freelance or is this is the limit of the trend window.
Kindly see the attachment
Kindly advice!

Hello,
Try increasing the Higher range value in trend configuration. In case of 800xA we have this option. Not have idea on freelance.
Is a behavior of Freelance.
Values above 999999.0 will be displayed in
exponent format.
Am I right that the problem is not the exponential display but the number of digits used in the exponential display? Unfortunately the exponential display uses also two digits precision, but has only one digit before the decimal point (and useless leading zeroes in the exponent).
In my opinion this should be changed. You should report this as an issue.
On the other hand, you must anyway be careful with what is possible with 32 bit floating point numbers. The relative precision is around 1e-7, so repeatedly adding 0.1 to 1e6 may not give the expected result.
Best regards
Jürgen
