Bahi, 

 For the list of VHDL constructs supported by Quartus II, open the Quartus II help and search for "Quartus II VHDL support".  Quartus II can't synthesize non-constant real objects or values.  If you need to implement reals in VHDL for Quartus II, I suggest you take a look at the floating-point adder/subtractor, multiplier and dividers megafunctions.  --jmv
