WebSep 30, 2014 · Robert_Crovella September 30, 2014, 3:34pm #2. When I modify this line of code: float a = (float) (1-2* (offset%2)); To this: float a = (float) (1-2* ( (int)offset%2)); your test passes for me. (I think comparing floating point types for exact equality is a bit risky though.) The size_t type of offset is being propagated through the ...
