Math Calculator

• example of typical function:
sin(2/pi) = 1 (this calculator always shows radian result)
sin(2*pi) = -2.4492935982947064e-16 (nearly zero)


• example of non-typical function(sum, avg, min, max):
sum(1,2,3) = 6 (use , (comma))


• example of binary operators:
1 < 0 = 1 (0 is true, 1 is false)
