floating point to binary

hi..
how can i convert value 0.3 and -0.3 to binary to store the binary value in my rom?
can anyone give an idea.
should i do it like this.....
i try to convert it to 8 bit.
so the last bit is for the sign number. then i get the answer is 00010011 for value 0.3 and 10010011 for -0.3.
my answer is correct or not?

Can't be said, unless you specify a number range and a representation. You apparently selected -2..+2 and
sign/magnitude representation. 2s complement would be a rather common representation. The range however can be
choosen arbitrarily.

i'm a newbie at vhdl, but i think i'd rather convert it to 4 bits with other signal as a flag.. but it depends on how i want to use it..

can i do that??
