MATLAB - realmin Problem or BUG
A new problem/bug found in MATLAB
Real max of MATLAB is:
real max = 2 ^ 1024 - 1
That is the same as realmax of MATLAB!
To calculate you should get the series as 2 ^ 1023 + 2 ^ 1022 + 2 ^ 1021 + 2 ^ 1020 + ...
Real min of MATLAB is:
real min = 2 ^ -1074
BUT realmin of MATLAB = 2 ^ -1022
To prove the real min of MATLAB, you could test so many equation. You'll get that no change in the value!
Because the assigned bits to this floating point system is 53 = ( 1074 - 1022 ) + 1

خدایا
خدایا رهاندی مرا چون بار اولی ها
خدایا پناه برم به تو از بدی ها
خدایا همواره بودی بر بالای سر گم گشته ام
خدایا التماس خیر دارم برای همسر و خانواده ام
خدایا بعد از این همم مرا ارشاد کن
خدایا لبه بد و خوب بر من نمایان کن
خدایا سنگ بر مسیر کنجکاوی های آلوده بنه
خدایا صبر در ره گرفتاری های ناآموخته بده
خدایا آگاه ساز مرا ز نیت پلید بدخواهان
خدایا فرمان ده برهم زنم عادت روزمرگان
خدایا به حکمت آزموده سازم در این دنیا
تا سرانجام شوم در امتحانت من علیا
