NIMCET 2014 — Computer PYQ

Consider the values $A=2.0\times 10^{30}$, $B=-2.0\times 10^{30}$, and $C=1.0$. Assume that the floating point numbers are represented with 32 bits (IEEE 754 Single Precision). What are the values of $X$ and $Y$ when the following sequence of operations are executed on a computer?

$X=A+B$

$Y=A+C$

$X=X+C$

$Y=Y+B$
