-76.0205078125 in simple binary => 1001100.0000010101
so, -76.0205078125 in normal binary is 1001100.0000010101 => 1.0011000000010101 * 2^6

single precision:
--------------------
sign bit is 1(-ve)
exp bits are (127+6=133) => 10000101
frac bits are 00110000000101010000000

so, -76.0205078125 in single-precision format is 1 10000101 00110000000101010000000
in hexadecimal it is 0xC2980A80
