MAX6675 VHDL

[Francovps1999]

Hello... I have the task of communicating with the max6675 sensor from an FPGA (VHDL description). I have a huge question, and it seems that after creating the state machine, I should perform compensation, as I've researched. Bits d4 and d3 apparently contain fixed-point information. How could I convert them to floating point so that I can display it on the FPGA's 7-segment display? I would appreciate your help. Thank you.
