WebApr 13, 2008 · convert real to std_logic_vector Heres my problem: 1. 'integer' is only 32 bits. I am working with numbers greater than that uptil 48 bits. (e.g. 4.456E13) 2. My idea was to use 'real' numbers for all computations and then convert them to a std_logic_vector of 48 bits to output ports. So its not the floating point numbers that I'm worried about.
