Click the grey button to change the type. Click the purple button to input the numbers. When you input a big decimal in it, it will load very slowly (like if you input 0.142857, it may cancel about 2h...),but it won't get stuck.Just wait. Shift+Click the green flag to run faster (If you still can't understand how to use this calculator or you even can't open it, please tell me in the comment)
