These are using strict check:
|a-b|/|a|< tolerance and |a-b|/|b|< tolerance
Or perhaps you mean that for both CLOSE and CLOSE_FRACTION both cases above are calculated ? In which case I still do not understand what is the difference between "percentage units" and "fraction of absolute value".
Yes. Both tools use strict comparison. "tolerance" in above inequalities is measured in "fraction units". To get "percentage units" you need to multiply the tolerance by 100. Usually it's easier to think in "percentage units" form: a is different from b by x percent, but fraction tolerances are popular as well. Gennadiy
