Point Fixed
How do I encode the following fixed point binary number into biased normalized floating point form?
1010.10
It needs to have a 4-bit mantissa and 6-bit exponent.
I used to be able to do this about 3 years ago in A-Level Computing, but now I’m a second year university student and its all gone out of my head!!!
If you could explain your answer that would be terrific!!!
The normal format is
sign | mantissa | sign | exponent
the problem is you need a 6 bit mantissa to hold 101011 then a 4 bit exponent would be fine. Are you sure you’ve got the right bit values for mantissa | exponent and are the sign bits supposed to be all part of the 10 bits? You cannot ignore the sign bit for the exponent as it is negative.
