Your condition never matches 0 exactly. Why not? See the FAQ:
Try it like this:
x = rand(1,1);
maxIterations = 10000000; % Failsafe to prevent infinite loop
loopCounter = 0; % Failsafe to prevent infinite loop
value = abs(350-12.9-x-32.4498);
while value >= 0.00009 && (loopCounter < maxIterations)
x = x + 0.0001;
value = abs(350-12.9-x-32.4498);
loopCounter = loopCounter + 1; % Failsafe to prevent infinite loop
% fprintf('After %d iterations, x = %f and value = %f.\n', loopCounter, x, value);
end
fprintf('After %d iterations, x = %f and value = %f.\n', loopCounter, x, value);
You might get:
After 3038399 iterations, x = 304.650168 and value = 0.000032.
