Global scope:
npm install scalc -g
Local scope:
npm install scalc --save
Wrap your expression with double quotes or single quotes
scalc "your_expression"
scalc 'your_expression'
or without any quotes
scalc your_expression
E.x: scalc "1 + 5*(PI - 10 * 2^5)" or scalc 1 + 5*(PI - 10 * 2^5)
The result will be copid to the system clipboard, so you can easily paste to anywhere.
var scalc = require('scalc')
var result = scalc(your_expression)
