Public bug reported:
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.
For example:
in Degrees: Sin(90) = 1 (correct)
in Gradians: Sin(100) = 0.984807753 (not correct, must be 1)
in Radians: Sin(3.141592654/2) = 0.027412134 (not correct, must be 1)
This is very serious issue especially for surveying engineers and
cartographers who are working with angles on daily basis.
