how to convert real to std_logic

[sajjadesrari]

hello
i'm new in vhdl
i want to convert real to std_logic
(in fact i want to put the real value to the output so first i should convert
it to std_logic right?)
how can i do it?
thanks.

Try this:

vector_with_8bit <= conv_std_logic_vector( integer( r), 8 );

thanks but i couldnt check it because
i have problem in converting std_logic to real!!!!
i did this:
real variable := to_real(to_integer(signed(std_logic value)));

but with this error:
Error (10305): VHDL Type Conversion error at xorgate.vhd(54): cannot convert type "std_logic" to type "SIGNED"

what's this????
thanks...
