You did a really nice job! Thanks.

By the way by copying this block of constants in Dropbox and pasting to the display everything loaded into the correct registers, even the 4 extra digits in R.0. In settings I have "Decimal Point" set to "." Not sure if that makes a difference.
R.0: 5.8177641733144E-03
R.1: 0.199999779
R.2: 0.142841665
R.3: 1.107161127E-01
R.4: 0.086263068
R.5: 0.05051923
R8: 2.1E-26
R.8: 4.47569E-20
R.7: 5.55391606E-14
R.6: 3.281837614E-08

Thanks!

Hello Bob,

You might want to try the updated version. Now basic trigs are more accurate, with improved results near 90 degrees. Also, asin(0), asin(1), acos(0) and acos(1) return correct answers instead of Error 0 messages. Hopefully no more mistakes :-)

Yes, DECIMAL POINT IS COMMA here. I have yet to test the simulator with other settings.

Regards,

Gerson.

P.S.: Here's the dropbox link to the updated version:
