http://d.puremagic.com/issues/show_bug.cgi?id=4455 Summary: Taking the sqrt of an integer shouldn't require an explicit cast. Product: D Version: D2 Platform: Other OS/Version: Windows Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: nobody@puremagic.com ReportedBy: dsimcha@yahoo.com --- Comment #0 from David Simcha <dsimcha@yahoo.com> 2010-07-13 13:56:00 PDT --- This one's been around for ages, but has just now started bothering me enough to file a bug report: import std.math; void main() { uint num = 1; auto ans = sqrt(num); } Error: test.d(5): Error: function std.math.sqrt called with argument types: ((uint)) matches both: std.math.sqrt(float x) and: std.math.sqrt(real x) I guess the solution is to make long and ulong overloads that forward to std.math.sqrt(real x). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

So I think a double sqrt(double) too can be useful, to avoid the useless argument passing of 10-12-16 bytes (necessary for an argument of type real) for the computation of sqrt on a double. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
