Question: The floor brackets are not displayed on plots -- why?


If I input 'floor(5.5)' in Maple 2018 I get the expected \lfloor 5.5 \rfloor thing.  I mean, with the special brackets typical for the floor notation.

However, if I try to place the floor notation onto a plot I get literally the string "floor(5.5)".  As in

  textplot([2, 2, 'floor(5.5)'])

The ' ' quotation marks ensure the delayed evaluation but I do not get the floor parentheses! 


  textplot([2, 2, 'sqrt(5.5)'])

outputs the radical notation as expected.

How come I cannot produce a plot with the floor brackets notation in it?
