A Simple Scientific Calculator

• Use it as a regular calculator.

  For example, typing in 5+3= will produce 8.

  Typing in 20.9 sin will produce 0.88715, i.e., sin(20.9)=0.88715.

• Still under construction: more functions need to added and appearance needs to be improved

  I'm working out such problems as 2.3.2*4.9=, i.e. invalid operand(s) involved.
