it once took me almost an hour, to find a '==' which |
|
440 |
should have been an '=' (you cannot compare floats with ==) |
|
19 | 441 |
(well, I looked at the '==' at least 50 times - |
442 |
- but didn't think about it ...). |
|
443 |
thats reason enough to add this check here. |
|
444 |
I will add more as heuristic knowledge increases ... |
