Problem: Inaccurate Sum in the Grid

The sum of the several summands in the grid view may not equal the overall time shown for the parent of the items.

Cause

The values in the data columns are rounded. For items that are sums of several other items, such as a function with several stacks, the rounded sums may differ slightly from the sum of rounded summands.
For example:
Module / Function
Time (exact)
Time (rounded)
foo.dll
0.2468
0.247
    
foo()
0.1234
0.123
    
bar()
0.1234
0.123
The rounded values in the grid do not sum up exactly as (0.123 + 0.123) != 0.247.
