Supposing that you saved your user-defined function (program) under the name 'CLONZ', just run any of the 50g's solvers on the equation 'N=CLONZ(G,W)'. I just tried it, and it's very slow but it works. Hint: Immediately after pressing the SOLVE key, press any other key, and the 50g solver will display each iteration at the stop of the screen, which lets you watch as it converges on the solution. Since LongFloat's accuracy is controllable, be sure to set DIGITS as small as possible to speed up the process.

Example: If N=1500, and G=153, the 50g's solver says that W=.991816725459
