DailyUI 004

Fourth day of Daily UI! Today it has taken me way longer than I expected. Somehow just couldn't make it looking like the way I want. I designed the calculator for both normal use and scientific use.
I put the num pad and equal sign to the right because it is easier to use when holding with one hand. Also since I always hated the x^2 on calculators (I always needed an exponent other than 2... I feel it's practically useless without being able to enter the exponent), I added the exponential function in the basic calculator.

For the scientific part, I added a ring with all the common complex mathematical expressions when holding down the equal sign. I think this could be a convenient way to have a basic calculator that can also fit the average user's need for a scientific calculator once in a while. Because truthfully, how many times have you really needed a scientific calculator? Probably only a handful of times. But when you do need it, you probably don't want to take the time to download another calculator.

On a last note, I have also included a second screen on the top for history. I think everyone has had the pain of having done an equation and needed to use the result in the next equation. So I just thought it'd be useful to have a history panel always accessible.
