Feature description

Issue: square root is treated as a binary operator (left * sqrt(right)). Square root is a unary operator.

Suggestion: when the user presses the "square root" button the behavior should depend on what is currently in the active input:

1. Just a <value> → √<value> →<result>
   (Or just value → result)
2. <value> and <operator> → <value> <operator> √ [waits for value]

If #2 requires a major rework, keep the current behavior of → <value>√[waits for value]

Why do you want this feature?

Practical use of sqrt requires re-entry of result. Also, the current handling of sqrt is not how calculators normally work
