Does PowerBI apply rounding when applying aggregations (SUM)?

Hi all

 

I have the below sample data set. 

 

IdentifierValue
A0.05
A0.2925
A0.1575
A0.065
A0.034
A0.065
A0.136
A0.1
A0.1
B0.034
B0.2925
B0.136
B0.1
B0.1575
B0.1
B0.065
B0.05
B0.065

 

I plotted a table with two columns -  'Identifier' and 'Sum' and am interested to flag out exceptions. Exceptions are identifiers whose total sum of all rows does not equal to 1.

In the above 2 instances, the sum of all rows with Identifiers A / B add up to 1 in Excel. However it flags as an exception when applied in PowerBi. Can anyone explain to me why that might be the case (I am thinking it could be a rounding issue in Powerbi) and whether there are any ways to resolve this? I do not want Identifiers A / B to be flagged as exceptions.

 

Thanks in advance.
