HP-35 style trig functions

Reviving an old thread, but it's on the same topic:

Base 10 CORDIC works fine for sine, cosine, and arctan. I'd like to use it for arcsin as well so I don't have to use identities that would require extra calculations. I found an example that calculates arcsin by comparing Y to the argument to arcsin every iteration instead of comparing Y to 0 as with arctan: link

It works with the base 2 algorithm but I can't get it to work with the changes made for base 10. Is there a way to do it?
