Current design of calculation from engine perspective is as add brackets after press "=":
Engine formula example:
1+2
=
(1+2)+3
=
((1+2)+3)+4
=
It cause many problems. The brackets are hidden, and it is very hard to implement official bracket support (there is a problems with Clear and backspace feature), and add new functions to it (sin, cos, tan, ln, sqrt etc), which are using brackets.
It also cause dramaticly performance drop with long calculation (try to even press several times "=")
My idea is store calculate values in some memory.
Example:
Engine formula example:
1+2
=
3+3
=
6+4
=
Where I could store previous calculated values?
What do you think about idea? |

Example:
Engine formula example: Array:
1+2 (nothing in array)
=
3+3 (1+2)
=
6+4 (1+2)(3+3)
=
10 (1+2)(3+3)(6+4)
C
6+4 (1+2)(3+3)
C
6 (1+2)(3+3)
C
3+3 (1+2)
Previous expression should be store in internal array. |
