It never made it out of its test phase.
Currently, input is only accepted from the buttons.
NOTE: While the main display field
seems to accept keyboard input, the software only reads keyboard
input in the modulus field (step 1) and registers (step 8).
- First define the modulus by entering its value in the topmost window
(clicking the "Enter Modulus" button is no longer necessary).
- Enter an integer by clicking on numeric buttons.
- Most operations (including greatest common divisor, "g") are binary and are entered in "infix" form.
- Enter the second operand.
- Click on the "=" sign to perform the calculation.
- Example: With modulus m = 50, clicking the four buttons
6 * 9 =
will yield the answer 4 since 6*9=54 and 54 MOD 50 = 4
- The greatest common divisor of integers a and b is
obtained as follows:
For example, the greatest common divisor of 192 = 2 6 * 3
and 30 = 2 * 3 * 5 is 2 * 3=6. Note that this is independent
of the modulus m: the answer will be the same no matter what value
- click in the digits of a,
- click on the gcd button.
- click in the digits of b,
- click on the = sign.
- New! You can now enter values directly from the keyboard into
