Math Problem Statement
Convert the value CCCCbase16 in the textbook floating point format to the corresponding value in decimal. Do not include spaces or any unnecessary symbols in your answer.
Solution
To convert the value in the textbook floating-point format to its corresponding value in decimal, we first need to understand the floating-point format used in the textbook. Typically, floating-point formats include a sign bit, an exponent, and a mantissa (or significand).
For this problem, I will assume the standard IEEE 754 single-precision floating-point format (32 bits), which is commonly used in textbooks. This format is structured as follows:
- 1 bit for the sign (S)
- 8 bits for the exponent (E)
- 23 bits for the mantissa (M)
Let's break down :
- in hexadecimal is in binary.
Thus, in binary is:
Next, we will pad this to fit into a 32-bit floating-point format:
Now, we divide it into the three parts of the IEEE 754 format:
- Sign bit (S): The first bit is 1.
- Exponent (E): The next 8 bits are 10011001.
- Mantissa (M): The last 23 bits are 10011001100000000000000.
Step-by-step Conversion
-
Sign bit (S):
- (which means the number is negative)
-
Exponent (E):
- Convert this to decimal:
-
Bias adjustment:
- IEEE 754 uses a bias of 127 for single-precision numbers.
- Actual exponent is calculated as :
-
Mantissa (M):
- Mantissa is in binary where is the fraction part.
- Converting to decimal:
-
Combine the parts:
- The value of the floating-point number is:
-
Calculate the final value:
Perform the calculation:
So, the value in the textbook floating-point format corresponds to in decimal.
