# Should we have a [calculator] tag?

Example questions:

Much like , , or , calculators are one of the first things one may be asked to program in order to learn a language. I think it would be helpful to have a tag for the many calculators.

So, how about ?

• Yes, definitely. The question should be: what should be the defining characteristics of a calculator? – 200_success Feb 12 '15 at 11:56
• It does arithmetic on input numbers. ... with that being the main goal. – Pimgd Feb 12 '15 at 11:56
• I guess your real question is; is a tax calculator worthy of the calculator tag? That I don't know just yet. – Pimgd Feb 12 '15 at 11:57
• We didn't have a tag for this already...? Strange! – Simon Forsberg Feb 12 '15 at 12:39

Yes, go ahead and create it. The Stack Overflow tag has the description:

This tag is for questions about calculators, or calculator programming.

I would recommend reusing the excerpt, like:

This tag is for questions about calculators.

but adding the wiki text:

Calculator questions have the basic concept that it supports the input of a sequence of values and operators, and the program computes the result. The format used for the input, whether it is Postfix (also called RPN - Reverse Polish Notation) like 3 4 + or Infix like 3 + 4 should be clarified in the question

• Thanks for wiki texts – Pimgd Feb 12 '15 at 12:40
• Evaluating postfix and infix expressions would be better covered under math-expression-eval. We might want a narrower definition of calculator. – 200_success Feb 12 '15 at 17:38
• Why not include prefix notation for 100% coverage? This pedantry in the tag might preempt pedantry in the comments. – ben rudgers Feb 14 '15 at 0:28
