Degrees for trigonometric functions?

[soshimee]

I need degrees for what I am doing, and radians won't work. Converting from radians to degrees with high accuracy doesn't seem to possible.

I’m not sure if PI is exposed in the API,† but you can get one from e.g. Decimal.atan(1).times(4). Once you have a representation of π you can convert to/from degrees by multiplying/dividing by π/180

†: If not, it probably should be, https://github.com/MikeMcl/decimal.js/blob/master/decimal.js#L32 defines it to 1025 digits and https://github.com/MikeMcl/decimal.js/blob/master/decimal.js#L3168 is a helper function that makes a Decimal out of it.

What makes you think it is not possible?

It is straightforward but I am not inclined to do the work for you.

Decimal.set({ precision: 100 });
pi = Decimal.acos(-1);
