Power operator in Chisel

I am trying to find an equivalent of Verilog power operator ** in Chisel. I went through Chisel Cheat sheet and tutorial but I did not find what I was looking for. After going through designs written in Chisel, I found that log2xx functions are popular choice while the power operator is never used. Of course I can always use the shift operator to get power of 2 but I was hoping that there is general power operator in Chisel. I tried to use scala's math functions to the job but I got compilation error.
