In my IDE, my console prints good answer ( 12.5663706143592 ) But when I submit, jury says like below.

wrong output format Expected double, but "12,5663706143592" found

I tried many encoding settings — including ASCII, Unicode, UTF-8 — because I thought it is encoding problem. However, all submission ended up with this failure.

I'm using C# and submitted as MS C#.

I hope this problem to be fixed soon so other's don't suffer assuming incomprehensible cause of test failure.
