3. Usage
3.1 General Usage
To reiteriate, the numbers must be added to the stack before an operation
may be performed. Most of the functions should be self explanitory;
however, some of the abbreviations may not be so clear. In
addition, there is a keyboard shortcut for every key.
3.2 Entry and Stack Manipulation
The stack is a very useful construct. It stores numbers on which
to operate until you are ready. This allows one to more easily control
the order of operations. To place an element on the stack one must
type in the number, which will appear below the stack. Then one may
press either Enter, to simply add the element to the stack or an operation
button, which will add the element to the stack and perform the appropirate
operation. The buttons which pertain to entry and stack manipulation
are along the right side of the stack.
-
Clear: This button removes all the elements from the stack.
-
Delete: This button removes the most recently added element.
-
Swap: This button will swap the most recently added element and the previous
element.
-
Flip: This button will flip the stack from the topmost element selected
to the bottom.
-
Float: This button will raise the selected element by one.
-
Sink: This will lower the selected element by one.
-
Roll: This will move the every element in the stack down one from
the element selected and place the bottom most element just above in the
place of the selection.
-
Undo: This button will undo the most recent operation, entry, or stack
manipulation.
-
Cancel: This will cancel an entry one begun so that an operation will operate
on the stack and not the incorrect number entry.
-
Backspace: This will backspace the last digit of the number entry.
-
Exponential Notation : This will allow the number to be entered in exponential
or scientific notation.
In addition, the base of the stack and entry may be changed by pressing
the 'Base' button on the right just above the stack Simlarly,
the unit of measure for trigonometric functions may be changed by pressing
the 'Angle' button.
3.3 Operation buttons
There a variety of operations that may be performed. For clarification
x is the most recently added element, and y is the previous element.
The following may not be self-explanitory:
-
% - Modulous
-
+/- - Negate - This may be used in entry as well as a stack operation.
It may also be used to negate the exponent in exponential notation.
-
y^x - Raise the y to x.
-
y^1/x - Find the xth root of y.
-
x! - x factorial
-
Ln - find the natural logarithm
-
log - find the base 10 logarithm
-
1/x - find the inverse of x.
-
AND - Bitwise AND
-
OR - Bitwise OR
-
Cmp - One's compliment
-
Arc/Hyp - These toggle buttons change the meaning of the trigonometric
buttons. Hyp will make the Sin button perform the hyperbolic sine.
The Arc button will make the Sin button find the Arcsine.

buttons.
