1. Represent 25.125 using IEEE 753, 32-bit format

Computer Science/Engineering

Here is an example he did ignore this if you already know how to do it

Eg. -26.875 in IEEE 754, 32bit format

Sing bit = 1

26.875 in normal binary = 16 8 4 2 1 . 0.5 0.25 0.125 = 11010.111

Sci format = 1.1010111 exp 4 + 127 = 131 (this is in Decimal)

Rep 131 as a byte = 1000 0011

Put it together

Sign bit, exp, mantissa

1 10000011 11010111000...(to make it 32 bits in total)

User friendly in HEX

Group them from left side

C1 D7 00 00

Endian =

Big Endian format (mac, unix) b/c large bytes are left

Make the greatest byte to be the smallest, etc.

00 00 D7 C1

Little Endian format (windows) b/c little bytes are left
