modify convert procedure to limit the output precision for some results |
accept input "trace" (should only be provided for precipitation) to display "trace" counted as value 0; text can be set, for example |trace=TR per request at Template talk:Weather box#Suggestion: trace precipitation should show up as "T", not as "—" |
