http://d.puremagic.com/issues/show_bug.cgi?id=4805 Summary: no equality between iota and double literal Product: D Version: D2 Platform: Other OS/Version: Windows Status: NEW Severity: normal Priority: P2 Component: DMD AssignedTo: nobody@puremagic.com ReportedBy: andrej.mitrovich@gmail.com --- Comment #0 from Andrej Mitrovic <andrej.mitrovich@gmail.com> 2010-09-03 10:18:34 PDT --- From this unittest in the documentation: http://www.digitalmars.com/d/2.0/phobos/std_range.html#iota import std.algorithm; import std.range; void main() { auto rf = iota(0.0, 0.5, 0.1); assert(equal(rf, [0.0, 0.1, 0.2, 0.3, 0.4])); } This assertion fails. I'm not sure if it is because of floating-point representation being different(?) or if this is really a bug. But its in the docs, so the code either has to go or there's a bug. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

I changed the docs to say approxEqual instead. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
