Hi Bob,
KFLOP has a double precision asin() function as well as a single precision asinf() function that would be slightly faster. I think both execute in less than a usec.
to make a table of floating point values in C you might do something like:
float TableA[5] = {1.0, 2.0, 3.0, 4.0,5.0};
float TableB[5] = {1.0, 2.0, 3.0, 4.0,5.0};
then
result = asinf(TableA[i] * TableB[j]);
I'm not sure what you mean by the "K-axis"
Hope this helps

Thanks for that Tom,
Of the 14 motors in my system, one is simply the K-axis.
