Fresh version of calQ available, an experimental calculator that gradually blurs the boundary between calculator, spreadsheet and coding.

At first use it as a simple online 4-function calculator, but with a ’till roll’ showing you your calculation history – yes just like the old mechanical desktop ones!

If you want, when you want and when you feel comfortable, click past values and to use them in your current calculation, or to reuse constants such as tax rates. Update past values and seen later ones change, just like a mini-spreadsheet. Name lines of calculations to them to help you remember what you’ve done.

If you find yourself doing the same thing repeatedly, copy an old till roll and edit it, export the till roll into a spreadsheet or use it to make a custom function.

But if you want just add things up 🙂
