# eight-bit floating point

Posted 29 January 2010 - 10:45 PM

what is the best approximation to the value one-tenth that can be represented using the eight-bit floating-point format described in this figure( the figure looks like this __ __ __ __ __ __ __ __ __ ]--Bit positions )

Sign bit Exponent Mantissa

I am confused with the question, I know the mantissa is the decimal part and the lines represent 1/2, 1/4, 1/8,1/16. Is the question just asking me to display 0 0000 0001=0.075 which is close to 1/10th? If someone could PLEASE just give me the answer so I could work it out

Is This A Good Question/Topic? 0

Try here.. there's a part that says "Convert 0.40625 to our 8-bit floating point format".. so something similar..
