Project Notes

(This project is the same as the project made by kevin_karplus except for one thing. If you attempt to divide by zero, it makes the division button flash.) This project is a simple reverse-Polish notation calculator. The biggest limitation is the use of scoreboards for output, as they are only capable of showing one decimal place of accuracy. Input and computation is maintained to the precision of the floating-point numbers, but there is no scientific notation (powers of ten). arctan is only computed to nearest degree (in squeak interpreter, but to full precision in Java interpreter). Now with backspace and exp(x).
