- need correctlyarrow_forwardSolution Floating point representation: It is defined as the representation of floating numbers. It includes sign bit, exponent, and mantissa bits. Based on precision it has 2 types. 1. For IEEE 754 single-precision floating-point numbers, what is the exponent of a denormalized floating-point number in decimal? Solution: In IEEE 754 single-precision, exponent bits are 8. Therefore exponent = 2 ^(n-1) -1 = 2^(8-1) -1 = 127 OPTION D 2. For IEEE 754 single-precision floating-point numbers, how many bits for mantissa? Solution: In IEEE 754 single-precision, there are 23 bits for mantissa. sign = 1 bit exponent = 8 bits mantissa = 23 bits 3. For IEEE 754 single-precision floating-point numbers, which of the following is an example of NAN? Solution: In IEEE 754 single-precision, NAN is a special value where all exponents bits are 1's and the mantissa is non zero. a. 1 111 1 111 0000 0000 1101 0000 0000 0000 Exponent is not all 1's.

- This question requires you to convert 4410 into the floating point format from the textbook and presented in class. (In all of the following parts you may use spaces to help you write and read your answers. Spaces are ignored by the automatic marker in this question.) • First, convert 4410 to binary and enter the answer here On paper normalise the answer so that it starts with 0.1 and calculate the power of 2 which will be the exponent value in the floating point answer. • Enter the normalised value here (it must start with 0.1, only enter as many digits as you need) • and enter the exponent of 2 here (it must be a decimal value) • Enter the full 16 bit binary version of the floating point representation of 4410 (it must be binary and it must have 16 bits)arrow_forwardWrite a C++ program that computes for the sum, difference, product, and quotient of two floating-point numbers with two decimal places in the quotient.arrow_forwardWhich of the following C# types cannot contain floating-point numbers? a. float b. double c. decimal d. intarrow_forward
