    Default Circle coordinate calculator: New updated more flexible version

    A comment on the previous thread started me thinking about how to improve the utility. It now is much more flexible in specifying the arc length and position. It also now will calculate the length of a flat (chord) for any number of flats (max 360) within any arc up to a full circle.



    It is only 41kb

    A worthy improvement, but with a bug in the angle readout.

    Using exactly what settings? It is probably a formatting error. Just curious, does a value of 313.1 make sense?

    The angle values should be

    231.00
    244.83
    258.66
    272.50
    286.33
    300.17
    314.00
    327.83
    341.67
    355.50
    009.33
    023.17
    037.00

    The ones indented printed out erroneously.

    Download it again and try it. I found a small roundoff error for certain values that produce formatting problems.

    Without knowing the settings you used the results aren't meaningful.

    Unfortunately, computers do not always produce accurate results even for rational numbers. This because the math is done in binary and then converted to decimal. For instance, In binary 0.001 is an irrational number.

    The corrected values shown above are for the settings in your OP. I cannot download it unless you make a Mac version.
