Round results
- In the Calculator app on your Mac, choose View > Decimal Places, then choose the number of decimal places to display. Calculator stores the full value and displays the rounded value. If the displayed value shows fewer decimal places than you specified, the undisplayed decimal places are zeros.
Enter complex equations using Reverse Polish Notation (RPN)
- In the Calculator app on your Mac, choose View > RPN Mode.The stack is shown in Calculator’s display, the Equal Sign key (=) becomes the Enter key, and four keys appear for manipulating numbers on the stack.
- Do any of the following:
- Swap the bottom two numbers on the stack: Click the Exchange Registers key .
- Move the most recently entered number up or down on the stack: Click the Roll Up key or Roll Down key .
- Remove the bottom number from the stack: Click the Drop key.
Correct unexpected results
In the Calculator app on your Mac, do any of the following:
- Repeat the calculation, keeping in mind that Calculator uses the fundamental order of operations to evaluate expressions. For example, multiplication operations are completed before addition and subtraction.
- If the programmer calculator displays numbers in an unexpected format, change to octal, decimal, or hexadecimal format: click the 8, 10, or 16 key, respectively, under the calculator’s display. Or use the basic or scientific calculator.
- If the result contains no decimal points:
- Choose View > Basic or View > Scientific, because the programmer calculator truncates all digits after the decimal point. For example, if you enter 99 / 10 =, the result is 9. Use the basic or scientific calculator to get more precise results.
- Choose View > Decimal Places (in any calculator), because the number of decimal places may be set incorrectly and the calculator rounds the result. For example, if decimal places is set to zero and you enter 99 / 10 =, the result is 10.
- If you’re not sure you entered the calculation correctly, use the Paper Tape (choose Window > Show Paper Tape) to review what you entered.
