### [DM15L M1B V28] All trig is in radians when in complex mode.

**Thu Apr 28, 2022 11:39 am**Hi. I seldom use trig functions and when I do, it's often radians. But I just needed to do some trig in degrees, and my DM15L gave me result in radians no matter what I did (tried grads, then degrees again, toggled all three modes, etc). The annunciator works as expected and shows nothing in degrees, or (G)RAD in the other modes. I thought the memory may be corrupt and did a reset, and degrees worked again. But, as soon as I put my DM15L in complex mode, the problem reappears. Just radians. Switching off complex mode (CF 8), and everything is fine again.

I kind of see why complex mode and radians are connected "mathematically", but I do expect keyboard calculations of trig functions to yield degrees when in that mode. So either the annunciator should "lock" to "RAD" when in complex mode, or the trig modes should work as expected.

Is it a bug, or is it me who doesn't understand how it supposed to work?

Edit, sorry, forgot to check my FW: M1B V28
