I am very happy that my DoyleCell node script is partly working.
It is producing the roots and circle centerpoints and master radius, but with 17 digits.

There may be a problem in nodeeditor with having 17 digits, or decimal digits. (FALSE, NOT A PROBLEM)
Circle node is not working with a radius of 17 decimal digits.
r = 0.43384321812883486

I am trying to apply javascript round to get 14 digits, code from the internet, which so far is not working.

// round(1.005, 2); // 1.01
function round(value, decimals) {
return Number(Math.round(value+'e'+decimals)+'e-'+decimals);
}

There are some sort of javascript limits on numbers...

Attached is non-functional DoyleCell node.
doylefn.js is a helper function which solves for the two root, which are a modulus and an angle argument,
and is a slightly modified program of Robin Houston. It mimics perlinnoisefn.js.
doylefn.js is supplying the required master numbers.
doylecell.js is the node program.
Place both .js programs in the nodeeditor extension folder.
A little more work is needed...
