Is there a command for arccosine?
hi,
··· Anyone know how to convert·an argument to an angle? for instant 'arccosin·x'. ·

On the other hand, a solution to your problem as first stated without "arcosin x" you will have to examine the total picture to find a solution. For example, in my application I use data from 0 to 4095 to give degrees and tenths using a formula given by poster Tracy as x ** 57600 but I changed it to x ** 57615 to closer fit my data to desired results.
So it depends on exactly what you want in terms of both input values and angles output which requires more details for me to comprehend than you have provided.

angle = x ATN y
where x and y are between -127 and +127 (representing +/- 1) and angle will be from 0 to 255 brads.
But you have x and want arccosine x. You can find y, and then plug it into the above formula.
On a unit circle, y*y = 1 - x*x. That is for a calculator, but on the Stamp for trig functions,
y = SQR (16384 - (x*x))
And
angle = x ATN (SQR (16384 - (x*x)))
For example, x=64, then y=111, angle = 42 brads.
In normal trig, that is x=0.5, y=sqr(3)/2, angle = 60 degrees, pi/3 radians.
edited: 60 degrees is ~42 brads

There is a work around for the "Help" file issue that you are experiencing.· If you click on "Start" in Windows and then click on "Programs" and then click on the "Parallax" folder you can open·the "Help" file from there.
