Calculate in degrees when using the degree symbol, otherwise in radians

[Former user]

Originally reported on Google Code with ID 203 ``` I would like to see Speedcrunch behaving more intelligent when using angles.

Issuing sin(90°) should result in 0 just as sin(pi/2), and sin(90) should result in 0.89... and sin((pi/2)°) should result in 0.02...

Having to switch is unnecessary and should be optional. I propose either to remove the different angle modes completely or add the suggested "auto mode" as an third option. ```

``` One problem is that the ° character is not available in all keyboard layouts. ```

``` Well, then perhaps it would be sufficient to replace the "°" Symbol with (2*pi/360) transparentely when in radians mode, so people with a keyboard layout missing the degrees symbol wouldn't have to deal with anymore GUI clutter, and the rest is happy with the added convinience. ```

``` In general, you cannot avoid a degree setting mode, because the inverse trigonometric functions like asin would not know what range to take the result from, then.

``` Just an idea that just came up:

sind(a) / sinr(x) asind(x) / asinr(a)

and so on... At least the ° symbol idea doesn't make much sense to me, but not sure about this one. ```
