Hi,

I am trying to keep a running total, where when ever an event occurs add 0.36 to the total. At the moment I have it adding 1 each time:

Code:

signal DataCount : std_logic_vector(5 downto 0) := "000000";
DataCount <= DataCount + 1;

*Hopefully I have tagged the code okay.

I have spent most of today trying to find out how to use fixed point binary in VHDL such as 0.36 in binary. I believe this to be 00000000.01011011.

Will i need to use something other than std_logic_vector?

Many thanks
