The floating-point format to be used in this problem is an 8-bit ieee 754 normalized format with 1 sign bit, 4 exponent bits, and 3 mantissa bits. it is identical to the 32-bit and 64-bit formats in terms of the meaning of fields and special encodings. the exponent field employs an excess-7coding. the bit fields in a number are (sign, exponent, mantissa). assume that we use unbiased rounding to the nearest even specified

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !
