bit(binary digit) is for binary numbers with base 2
7 digit decimal number with base 10
1 digit for sign of exponent
1 digit for magnitude of exponent
1 digit for the sign of mantissa
so 7-3 = 4 digits are left for magnitude of mantissa
sign of exp | sign of mantissa | magn of exponent |
So Largest number = 0 0 9 9 9 9 9( 0 denotes positive number)
smallest number = 1 1 0 0 0 0 0 ( 1 denotes negative sign )

Use a 10-‐bit model for floating point numbers, where one bit is used for the sign bit, 4 bits are used for the exponent with a bias of 7, and 5 bits are used for the fraction. What is the smallest and largest positive normal value that can be represented?
Floating Point Representation Consider a computer that stores information using 10 bits words. The first bit is for the sign of the number, the next 5 for the sign and magnitude of the exponent and the last 4 for the magnitude of the mantissa. The mantissa is normalized as described in class and in the textbook. a. Convert 1 00010 1001 to a base-10 system b. What is the highest number that can be stored on this computer? c. What...
(30 pts) In addition to the default IEEE double-precision format (8 byte 64 bits) to store floating-point numbers, MATLAB can also store the numbers in single-precision format (4 bytes, 32 bits). Each value is stored in 4 bytes with 1 bit for the sign, 23 bits for the mantissa, and 8 bits for the signed exponent: Sign Signed exponent Mantissa 23 bits L bit 8 bits Determine the smallest positive value (expressed in base-10 number) that can be represented using...

6-bit floating-point encoding: 1 sign bit, 3 exponent bits, 2 frac bits( mantissa/significand) what is the exact 6-bit floating-point encoding for the following numbers: 17 0.5 -6 7.5 Please show the steps
Can you write process of the question? A fictional floating-point encoding scheme uses 1 bit for sign followed by 1 bit for the exponent and 2 bits for the mantissa. It otherwise behaves exactly like the IEEE 754 encoding scheme. List down all decimal values that can be represented by this scheme along with their binary representation.
