Calculate

Evaluate the text as mathematical expression.

The result is displayed as the action's button title. Clicking the action button will paste or copy the result. (Holding Shift (⇧) will always copy.)

Examples with simple arithmetic:

  • 1 + 1 → 2.
  • 15/2 → 7.5
  • (50 + 1) * 2 - 5 → 97.

It can also support quite complex expressions, as supported by mathjs:

  • 155 miles * 18% in km = 44.9006976 km
  • sqrt(4) → 2
  • sin(pi/2) → 1
  • 4(2 + 3i) → 8 + 12i
  • a = 2; b = 3; 2a + b → 7

If the input text ends with an = character, the result will be appended to the input instead of replacing it. For example:

  • 100/4= → 100/4=25

About

Author: Nick Moore

The extension is implemented using mathjs. The evaluation is performed using the evaluate() function of the library.
