What to change here such that final value never goes negative i.e (0<value<=0.00009) and x changes accordingly
x = 0.77;
maxIterations = 10000000; % Failsafe to prevent infinite loop
loopCounter = 0; % Failsafe to prevent infinite loop
value = (0.5-x);
while value >= 0.00009 && (loopCounter < maxIterations)
x = x + 0.0001;
value = (0.5-x);
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);

while value >= 0.00009 && (loopCounter < maxIterations)
newx = x + 0.0001;
newvalue = (0.5-newx);
if newvalue < 0.00009; break; end
x = newx;
value = newvalue;
loopCounter = loopCounter + 1; % Failsafe to prevent infinite loop
% fprintf('After %d iterations, x = %f and value = %f.\n', loopCounter, x, value);
end
