http://d.puremagic.com/issues/show_bug.cgi?id=4765 Summary: std.math.modf always returns 0 Product: D Version: D2 Platform: x86_64 OS/Version: Windows Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: nobody puremagic.com ReportedBy: etherous gmail.com --- The following code should output "3" but instead outputs "0". This is because, regardless of the values sent to std.math.modf, the returned value is always 0. I've used many combinations of values, but the result is always the same: 0. At first I believed I was misusing the function and I noticed that the second parameter was taken as a ref, so I performed the function call and checked 'b', but it always stored the beginning value unchanged. import std.stdio; import std.math; void main () { real a = 9., b = 5.; writeln(modf(a,b)); } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

The platform run on isn't what's relevant, it's if the app is a 32 or 64 bit app. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Kyllingstad <bugzilla kyllingen.net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bugzilla kyllingen.net 13:11:25 PST --- Actually, I think the documentation is wrong here. The C function modfl(), to which std.math.modf() forwards, does not calculate the remainder of an integer division. Rather it splits a number into an integer part and a fractional part (e.g. it splits 3.14 into 3 and 0.14). The C function to calculate the remainder is fmod(), which doesn't seem to have a counterpart in std.math. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
