Calculator

Updated v2.3.8

At a glance

  • A themed desk calculator available in every workspace — and from inside any numeric input
  • Functions, powers, and constants beyond what dimension fields accept
  • Paste a number or a whole formula, and copy the result back out with one click
  • Closes the loop with Quick Measure — measure, copy, paste, calculate
  • Launched from a value field, Use drops the result straight back into the input
  • Degrees/radians aware for trig

JetCad3 keeps a desk calculator built in so quick shop math never means reaching for your phone. Every workspace — Drafting, Design, Plasma, Laser, Router, and GcodePilot — has a Calc button right on its toolbar that opens it as a movable window you can leave open while you work (in GcodePilot it also keeps its c shortcut). In Drafting and Design it lives in the labeled Utility group next to Search, and it stays on the toolbar while you're editing a sketch. Value prompts that show a calculator icon beside the input — like GcodePilot's set/increment axis prompts — open it in a second mode with Cancel and Use buttons: work out the number, hit Use, and the result lands back in the field for you to confirm.

Beyond the dimension fields

Dimension inputs across JetCad3 already evaluate basic math — + − × ÷, parentheses, and unit suffixes like in and mm. The calculator picks up where they stop: powers (^), square and cube roots, factorial (!), percent, ln/log/exp/abs, the constants π and e, and the full set of trig functions (sin cos tan asin acos atan) with a Deg/Rad toggle so 45 means 45 degrees when you want it to. The mode you pick is remembered between sessions.

Views and keyboard entry

Two layouts toggle and persist: Compact, a plain four-column pad, and Scientific, which adds the function block. Every button is also a live hotkey while the calculator has focus — digits and operators type straight in, Enter is equals, Backspace deletes, c clears, and Escape closes (or cancels, when launched from an input). Buttons flash as you type so you can see the keystrokes register. The whole thing is drawn with the app's theme tokens, so it matches whatever look you've picked in Themes.

Copy and paste

The calculator works with your clipboard both ways. Paste (Cmd/Ctrl+V) drops in a value you've copied from anywhere — a measurement from Quick Measure, a number from another app — or a whole formula like 1+(2/3)*4, which evaluates the moment it lands. Pasted math is tidied into the calculator's own look, and a stray in/mm label is dropped since the calculator works in plain numbers. A small copy icon sits beside the running answer: click it (or press Cmd/Ctrl+C) to copy the result as a plain number that pastes cleanly into any measurement box. That closes a common loop — measure a part, copy the value, paste it in, do the math, and copy the answer straight back into your design.
