Thanks for reporting this bug and any supporting documentation. Since
this bug has enough information provided for a developer to begin work,
I'm going to mark it as confirmed and let them handle it from here.
Thanks for taking the time to make Ubuntu better!
** Description changed:
Binary package hint: gcalctool
Gnome calculator, i.e. gcalctool 5.24.1, presented in Ubuntu 8.10 does
not calculate correctly in gradians (gon) and radians units. In
scientific view, switched on the radio boxes of gradians or radians
- angle units, the calculator does not calculate correctly.
+ angle units, the calculator does not change the unit who stays in
+ degrees.
For example:
in Degrees: Sin(90) = 1 (correct)
in Gradians: Sin(100) = 0.984807753 (not correct, must be 1)
+ in Degrees: Sin(100) = 0.984807753
in Radians: Sin(3.141592654/2) = 0.027412134 (not correct, must be 1)
+ in Degrees: Sin(3.141592654/2) = 0.027412134
This is very serious issue especially for surveying engineers and
cartographers who are working with angles on daily basis.
Additional information:
gcalctool 5.24.1, Ubuntu 8.10 (intrepid), Kernel Linux 2.6.27-11-generic,
GNOME 2.24.1
** Changed in: gcalctool (Ubuntu)
