Description of the issue

If a field contains number represented in scientific notation AND the number is followed by a carriage return, e.g. 1.965311e-10CR, where CR is a carriage return, then the number is shown in a field as 196.531% when the field is set to display the number as a percentage and with 3 decimal points.

This only happens when the number is followed by a CR.

I believe in the example above that the field should display 0.000%
This is because a number not expressed in scientific notation AND followed by a CR displays correctly as a percentage.

Steps to reproduce the problem

1
Create a number field and set its value to this: 1.965311e-10CR (where CR is a carriage return)

2
Display the number in a field as a percentage, only showing the first three decimal places

Expected result

0.000%

Actual result

You see an incorrect number! = 196.531110000000%

Also note the extra "1" before the string of zeros... probably from the "e-10".
Whatever, its behaviour that is not consistent with the processing of other numbers with a following CR (which is simply ignored)

Exact text of any error message(s) that appear

No error message

Configuration information

Have only included 1 plug-in = BaseElements. Everything else is as standard as possible.

Workaround

Easy enough:
If using scientific notation...
- Ensure that there is no following CR and
- Force a rounding to less than 10 significant digits before storing the field.
