Multiplying float and integer literals in VHDL

Question

I'm working with VHDL-2002, trying to declare a constant in the following way

constant CORDIC_SCALE_FACTOR    :   integer := 0.607252935*(2**COORDS_WIDTH);

With COORDS_WIDTH being a previously defined generic. However, I'm not being able to perform this multiplication due to types. What I would like to do, is cast 2**COORDS_WIDTH to a float type, and then cast the result to an integer value (assuming the cast would take the real part of the float and assign it to the integer). How can I accomplish this? I've found resources on the web dealing with this type of conversion but not on literals, this should be easier.

Answer 1

Found the solution, it was pretty straightfoward. The 'float' type is named 'real'

constant CORDIC_SCALE_FACTOR    :   integer := integer(0.607252935*real(2**COORDS_WIDTH));
