conversion of negative floating point in binary using VHDL

[sougata_vlsi13]

I was literally stuck witha problem regarding the conversion of negative floating point in binary and to write it in VHDL.For example the num is -0.8.when i convert it into binary it is like .11001100.since it is -ve i have to convert it into 2's complement and to provide the extra MSB bit.
My question is that how to represent it in VHDL without using that decimal point.Plz kindly help me in this regard.

Did you read that 2's complement article on wikipedia I linked to earlier?

yes i read that article...i know about the representation but i dont know how to remove that decimal point while writing it in vhdl bcoz if i write with the floating point the code is going to be non synthesizable

I take it that multiplying by SCALE FACTOR as suggested in previous posts is something that happens to other people? Re-read old stuff, check scale factor.
