I came across a weird issue. I have a percent field with precision up to 4 decimal points. We have some calculations which populate the value of that field. What I can see is after calculations if the value is low, its shown differently in classic and lightning. This popped up during a demo. I tested this on classic and gave a demo in lightning(which went bad). Ideally it should be same, if anyone can throw some light on this, would be helpful.
Steps to replicate:
Create (14,4) precison % field
Update it value to a lower number.
update new Opportunity(APR__C=d,id='00628000007Y078AAC');
Try to view it in Lightning,Classic and Workbench. Each view will show different value.
