HI FELLOWS
I HAVE SOEM PROBLEM WITH FLOATING POINT ADDITION AS SHOWN BY THE
METHOD (FAST16) IN BLACKFIN EE185 NOTES FROM ANALOG DEVICES. THE
PROBLEM COMES WEN THE EXPONENT ARE DIFFRNT. example to multiply 3 and
0.5 . i detect the problem as in shifting the mantissa relative to
othere

That's what you are supposed to do. If you add 3 and .5 you need to get
3.5, not 8. If you don't shift the mantissa you won't get the right
answer.
