I just played around a bit with the calc module. My version only shows the suggestion if the result is different from the query. So conversion to integer is still a go while the 1 query 1 result suggestions are gone.
An intermediate solution has been integrated in the official package (to be released).
The rationale behind this choice is that the plugin cannot guess if user wants to calculate or to convert. More specifically, the version to be released will automatically return several results depending on its type and its nature. For example, an integer result will be declined in several bases (decimal, hexadecimal, octal and binary) and a floating point number may also be declined in normalized and/or scientific notation in addition to the normal display, if needed.
