deg <> rad function or variable #4

Is it possible to add a option for trigonometric functions to use degree or radiants as parameter?

As global setting to use sin() directly with degrees
or as predefined variable like deg2rad = pi/180
or a function deg2rad() / rad2deg().

Thanks for this really good piece of software for SailfishOS !

Thanks for your feedback. This is feature worth to consider in a future update. As an intermediate solution, you can switch to the scientific calculator mode and enter the "°" sign (not sure if it is available on all keyboards) to indicate degrees. For example,

sin(90°)

yields 1.

Thank you for the info. Maybe it's worth to update the function help with that.

Closed via d514eda57c1a55fea8e5dbecd4e4eb5c152510a3, which introduces two new functions, deg and rad for conversion between arc degree and radian.
