I've created some small tests about precision and one point I don't get
why the result end with 1 not with 3.
A bit surpriced

Hi @HennSarv ,
In power query, the largest precision that can be represented in a Decimal Number type is 15 digits long. The decimal separator can occur anywhere in the number. The Decimal Number type corresponds to how Excel stores its numbers.
Please refer: Data types in Power Query
You can also refer this similar issue: Decimal Values Precision

YEs I undestand this fine - My question is about last funcy number on "rounded" result
When You look my example - there ise 2 numbers with lot of 1-s and 2-s after comma
when You preserve only 15 digits - You get:
0.111111111111111
0.222222222222222
sum on those much be
0.333333333333333
but looks like
0,33333333333333331
1st - there is 17 numbers after and result must finish with 3 not with 1
actualli
0.11111111111111111 // 17 digits
+
0.22222222222222222
produces 0,33333333333333331
Possibly because a has 2 extra characters than b?
