This is a simple calculator for the Mac OS X. The calculator uses postfix/RPN notation for entering calculations. However, unlike a real world calculator, Calc does not have any keys. All number and operation entries are via the computer keyboard.
To calculate the 5 + 6 * 7 you would put the following on the stack
- 5 then hit <return>
- 6 then hit <return>
- 7 then hit <return>
- * then hit <return>
- + then hit <return>
- or enter the stack in one line: 5 6 7 * + then hit <return>
When all the numbers and operants are entered, the result will be on the top of the stack.
The following are operants that can be used in Calc
| Operations | Meaning |
| + | add two numbers |
| - | subtract two numbers |
| * | multiply two numbers |
| / | divide two numbers |
| ! | factorial of one number |
| ^ | to the power ( 2 3 ^ result: 8 ) |
| cos | cosine of an angle in radians |
| sin | sin of an angle in radians |
| tan | tangent of an angle in radians |
| log | base 10 log of a number |
| pi | value of pie |
