- Perform the following operations using 8bit signed 2’’s complement notation ?
(-56) + (-72)
(-73) + 84 - IEEE-32 bit floating-point representation for a single-precision number uses the format as: Sign ( bit 1 )bit biased exponent ( 8 bits) Significant (23 bits)
Using this format represent the following decimal numbers:
0.250
8
Now using the representation perform the following operations:
0.250 + 8
0.250 * 8
