Study Notes
Floating Point Numbers
- A decimal point separates whole numbers from the fractional part in the decimal system.
- Example: In 37.25, the whole part is 37 and the fractional part is 25/100.
Analysis of a Floating Point Number
- The number 37.25 can be represented through digit analysis:
- 3 in the tens place: (3 \times 10)
- 7 in the units place: (7 \times 1)
- 2 in the tenths place: (2 \times \frac{1}{10})
- 5 in the hundredths place: (5 \times \frac{1}{100})
- This representation aggregates to (37.25 = (3 \times 10) + (7 \times 1) + (2 \times \frac{1}{10}) + (5 \times \frac{1}{100})).
Binary Representation of Floating Point Numbers
- The binary equivalent is calculated by converting whole and fractional parts separately.
- For the whole part, methods include subtraction or division.
- For the fractional part, use either subtraction or multiplication.
Fractional Part - Multiplication Method
- Column values in binary representation are structured as: …, (2^5), (2^4), (2^3), (2^2), (2^1), (2^0); and fractional parts as (2^{-1}), (2^{-2}), (2^{-3}), etc.
- Each power corresponds to specific fractional values (e.g., (1/2), (1/4), (1/8), …).
Example of Conversion using the Multiplication Method
- To find the binary equivalent of 0.25:
- Multiply the fraction by 2 until reaching 0:
- (0.25 \times 2 = 0.5)
- (0.5 \times 2 = 1.0)
- Collect whole parts: the process yields (0.01) as the binary representation, where "1" appears after the binary point.
- Multiply the fraction by 2 until reaching 0:
Summary of Conversion
- Collect the whole parts in the order they appear after the radix point in binary representation.
- The methodologies provided effectively convert both whole and fractional parts into binary equivalents.
