My guess is that the calculator is doing the division before the multiplication, computing 100*(A/B), rather than (100*A)/B. Since you are dealing with integers, it is rounding A/B down to zero, and that is the end of it for you.

The calculator step lets you break a calculation down into multiple smaller components, all within the step. You can even specify which fields created in those substeps should stay in the stream, and which should are temporary values that should be discarded.

So try first doing a calculation such as tempValue = 100*A, then result = tempValue/B. Set Value type to Integer in both steps.

In the Calculator step, put 'Value type' as 'Integer'
