The results are inconsistent from run to run. A few times, I got Application output: a/b = nan Application error: core.exception.RangeError@/home/c891/c322.d(6): Range violation But most of the times, I get a "successful" run without any output. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

Are you sure you receive no output? It seems for me the code works as expected. If you provide no args, you will have array bounds exception (what actually happens). Additionally a is defaulted to nan, so the program will also print nan in this case. If you provide some float as a program argument, you will receive inf, -inf or nan depending on the argument. So, I don't see any problem here. I checked 2.061 on win64. If on other platform it does not work properly, please provide source and specify platform. Otherwise this issue can be closed. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
