Use Calculator to perform basic, advanced, or programmer calculations. If your Mac has a Touch Bar, you can easily do quick calculations—without even moving the pointer.

**Tip: **To learn a key’s function, hold the pointer over the key to see its help tag.

The newly renovated Luzhniki Stadium, with a seating capacity of 81,000 people, will soon be hosting the opening/closing ceremonies and final game of the 2018 FIFA WORLD CUP in Russia. McCauley Sound, Inc. And their Russian partners completed the installation of a new ILA412 / MLA3-2i long throw line array system ahead of schedule, for what is one of the largest soccer. “The VRX Line Array Calculator will provide an effective sound design and simulation tool that builds on the successful heritage of JBL’s VTX and VERTEC Line Array Calculator software.” With the VRX LAC, up to four audience planes can be modelled. Adding ground-level seating, multiple balconies, stage areas and rear wall boundaries is simple.

In the Calculator app on your Mac, choose an option from the View menu:

*Basic:*Perform simple arithmetic operations.*Scientific:*Use memory functions and perform advanced calculations involving fractions, powers, roots, exponents, logarithms, trigonometry, and more.*Programmer:*Perform binary, octal, decimal, and hexadecimal calculations, including bitwise operations. You can also view the ASCII and Unicode characters represented by the current value.

In the Calculator app on your Mac, enter the original value, choose Convert in the menu bar, then choose a category, such as Temperature or Currency.

*Note:*You must be connected to the internet to get the most recent currency conversion rate.

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.

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.

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.

If you prefer to display a comma separator, choose View > Show Thousands Separators to display the comma in larger numbers.

In the Calculator app on your Mac, use keyboard shortcuts to quickly enter calculations; the shortcuts vary based on the type of calculator you’re using.

Action | Shortcut |
---|---|

Clear | Esc C key |

Clear All | Option-Esc |

Negate the displayed value | Option-Minus Sign (–) |

Percent | Percent Sign (%) |

Divide Chrome firefox or safari for mac. | Forward Slash (/) |

Multiply | Asterisk (*) |

Subtract | Minus Sign (–) |

Add | Plus Sign (+) |

Equal | Equal Sign (=) |

Remove the most recently entered digit or letter | Delete key |

Action | Shortcut |
---|---|

Raise the displayed value to the power of the next value entered | Caret (^) |

Calculate the natural logarithm of the displayed value | E key |

Calculate the factorial of the displayed value | Exclamation Point (!) |

Exponential notation | Shift-E |

Action | Shortcut |
---|---|

Swap the bottom two numbers on the stack | Command-E |

Move the most recently entered number up on the stack | Command-Up Arrow |

Move the most recently entered number down on the stack | Command-Down Arrow |

Remove the bottom number from the stack | Command-Delete |

To show a running list of your calculations, choose Window > Show Paper Tape.

To perform advanced calculations involving equations and graphs, use the Grapher app.

**HARMAN’s JBL Professional is announcing the VRX Line Array Calculator (LAC) for its popular and widely used VRX Constant Curvature Series loudspeakers. The VRX LAC offers an accurate and easy-to-learn design tool that allows configuration of VRX systems prior to deployment.**

“Since JBL introduced the first VRX loudspeakers, they have been used in virtually every imaginable environment, from theatres to houses of worship, sports facilities to schools, as portable or permanent sound reinforcement systems,” said Jon Sager, Senior Manager, Market Development, Installed Sound, JBL Professional. “The VRX Line Array Calculator will provide an effective sound design and simulation tool that builds on the successful heritage of JBL’s VTX and VERTEC® Line Array Calculator software.”

With the VRX LAC, up to four audience planes can be modelled. Adding ground-level seating, multiple balconies, stage areas and rear wall boundaries is simple. In addition, quick calculation of optimal array angles and gain shading offers smooth front to rear audience coverage. Visual display of rigging details on a separate “Array Configuration” page shows size, weight, and rigging parameters with built-in working load limit (WLL) design factor safety warnings.

The VRX LAC also enables two separate arrays to be used simultaneously. Adding a second rear delay array with the proper angles and relative volume is now easily accomplished. Moreover, ground-supported stand mount and subwoofer stacked arrays can be modelled just as they are used with the VRX products. Dual angle pole mount socket selectors show down tilt angles for increased aiming flexibility, while single point hang array angles can now be easily checked ahead of time.

The VRX LAC includes a quick start help file that can get any VRX user up to speed and using the VRX LAC in under an hour. VRX User Guides (for both passive and powered systems) are bundled with the VRX LAC for quick reference to specific questions that may come up when using VRX loudspeakers.
