## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/calculator/binary-calculator/?input=1010&mode=bin2dec

## Inputs
- input: Input; type=text; optional; default=1010
- mode: Mode; type=select; optional; default=bin2dec

## Outputs
- result: Result; format=text; primary

## Formula
Binary and decimal values are parsed as base 2 or base 10; arithmetic is performed on integers and the result is formatted in both bases.

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.
