In a Label Tool is it possible to display value of a point, for example 3.2 (double type), with subscript after a dot, like that: 32 ?
You can use the custom functions shown in this answer to write an expression that will achieve this when labelling.
to_int( <VALUE> ) || subscr_num( to_string( to_int(abs(<VALUE> - to_int(<VALUE> ) )) * 10))
This will display the first decimal place as a subscript. Note that not all fonts have the unicode subscript characters, Lucida Sans is one that does work.
