I am experimenting with video signal generation. It would be nice if there was support

Or 'Token string here'

Yeah, that would make things a lot easier - same syntax like C++.

I think Axe needs trig functions because if I had to say: calculate and simulate the trajectory of an object, it would take a lot more memory to program each function and its values.

You don't need much Trig at all to compute the trajectory of an object, and Axe already has Sin and Cos, which should be more than enough

sin(x) returns a value between -127 and 127, where x is between 0 and 255. So if you want to get the sine of 90°, you type sin(64) and get 127.
It's the same with the cosine function.
If you want to plot the points on a circle with radius 10, you think of a number you have to divide 127 to get 10, which is about 13.
You also have to add the Center coordinates.
For(I,0,255)
sin(I)//13+20->Y
cos(I)//13+20->X
Pxl-On(X,Y)
End

I don't know which kind of routine is used. I once programmed a piston engine-simulation with sin and cos and that was pretty fast.

And if you do always the same calculation with the sin/cos values, I think it is better to use a LUT for only these 16 values.

The sin and cos routines are very fast, about the speed of doing one multiplication (because that's essentially what it does).  It uses the fact that sin(x) when x is in the range [0 to 180 degrees] has a hump that is approximately a parabola.  For the domain and range that I'm using in Axe, sin(x) is approximately: x*(128 - x)/32.  This is then just replicated with alternating sign periodically.

A look-up table is always faster, they are even faster than regular multiplication.  If you have 16 values, then done right it could be slightly faster and about the same size to use a look-up table, but you have to be good at Axe optimization to achieve this.  However, unless you are computing sin and cos more than 1000 times per second, I wouldn't even bother because it won't make a difference.
