Answer 1

Answer #1

78.75 in simple binary => 1001110.11
so, 78.75 in normal binary is 1001110.11 => 1.00111011 * 2^6

single precision:
--------------------
sign bit is 0(+ve)
exp bits are (127+6=133) => 10000101
frac bits are 00111011000000000000000

so, 78.75 in single-precision format is 0 10000101 00111011000000000000000
in hexadecimal it is 0x429D8000

Answer: a. 429D8000
