It is very confusing that formulas such as Sin do not calculate unless you put in units such as mm, pix, etc.

In the Transform panel, the calculation between numbers is done as it is, but functions such as sin are not calculated unless the units are entered. I am very confused.
The deformation panel will calculate the numbers, but when using functions such as Cos, Sin, etc., you have to put in the units for the calculation to work.
Example1: 20 + 40
　　　→ The number 60 is entered.Good!!
Example2: cos(33)
   → The result of the calculation does not change.Bad work

Example: cos(33)mm
→0.8　good...but.
Since you specified units such as mm, inch, px, etc. when you created the document, it is a good idea to use those units if you did not include them when you used the function.

Since mm and pix are specified in the document, it would be better to be able to calculate without putting in units.

I would guess that what is happening is as follows:

When you use pure numbers such as 20+30, you get a pure number that Affinity assumes is in the default unit.

When you use a trig function, the result is an absolute number with no intrinsic unit. It needs a unit applied to make it useable.

If w = 20 mm and h = w+30, then h = 50 mm. So if w = 33 mm and h = 20+cos(w), shouldn’t h = 20.84 mm?

Yes it should. I was exploring a possible reason why it was not. I would guess it it probably arises at a some very low level of coding.
