Normalisation

Question 1

What is normalisation

Answer 1

A technique used to represent numbers as precise as possible

Question 2

What is the precision in relation to when using normalisation

Answer 2

How many bits are being used

Question 3

Converting denary to binary floating point numbers
Step 1

Answer 3

Convert to a fixed point binary number in two’s complement

Question 4

What is the exponent used for

Answer 4

To ensure that the floating point is place to optimise the precision of the number

Question 5

Converting denary to binary floating point numbers
Step 2

Answer 5

Move the binary point in order that you mantissa is normalised, keep a note of how many times you must move the binary point

Question 6

Converting denary to binary floating point numbers
Step 3

Answer 6

Convert your exponent to binary

Question 7

Answer 10

The denary value will be negative and less than 1

Question 11

Define underflow

Answer 11

When a number gets too small to represent it by the number of bits available to store it

Question 12

Define overflow

Answer 12

When a number gets too large to represent it by the number of bits available to store it
