(no working required)
The binary bit pattern 10110110 has been represented in Sign & Magnitude. Convert this bit pattern into its denary format.
The binary bit pattern 10110110 has been represented in Two’s Complement. Convert this bit pattern into its denary format.
A student is performing a binary addition on the following numbers.
011011010 101110110
The outcome of the addition would be:
The error that this creates is:
Computers store binary as real numbers in a floating point representation.
Which two mantissas below are not normalised?
A normalised floating point binary number is represented using 9 bits for the mantissa and 5 bits for the exponent.
Calculate the floating point representation for the denary number 10.375
Mantissa =
Exponent =
A normalised floating point binary number is represented using 9 bits for the mantissa and 5 bits for the exponent.
Calculate the denary representation for the binary number:
Mantissa: 100100101 Exponent: 00110
Show your working by filling in the missing sections:

A floating point binary number is represented using 9 bits for the mantissa and 5 bits for the exponent. This number is not normalised.
Correct the representation so that the number is normalised:
Mantissa: 000100101 Exponent: 00110
Denary =
Corrected:
Mantissa: Exponent:
