So when you see values that look like 4 it means that it in the range 4 plus or minus the integer cuttoff threshold. If the value looks like 4.0 then it differs more from 4 than the integer cutoff, but less than six decimal places. Maybe it’s 4.000000002 , or 3.99999993 .
To see the real value, you must use a custom formatting component with an {0:R} format flag. The R flag will ensure that no information is lost when formatting a number.
