Study Notes
Floating-Point Numbers
- Decimal numbers use a decimal point to separate whole numbers from fractional parts
- Examples: 37.25 (whole = 37, fraction = 25/100), 123.567, 10.12345678
- A floating-point number is represented using a combination of an integer and a fraction
- The method to convert decimal numbers into binary
- Whole part: Subtraction or division (the previously learned method)
- Fractional part: Subtraction or multiplication
Binary Representation
- Binary equivalent of a decimal number can be found by calculating each part separately
- Example: In 37.25, 37 is calculated using the whole part method and .25 using the fractional part method.
Fractional Part - Multiplication Method
- To find the binary equivalent of a decimal fraction, repeatedly multiply the fraction by 2
- Keep track of the integer parts produced in each step
- The binary equivalent is formed by concatenating the integer parts in the order they were generated
- Example: To find the binary representation of 0.25, repeatedly multiply 0.25 by 2.
Fractional Part - Subtraction Method
- Start with the given decimal fraction
- Identify the largest power of 2 that is less than the given fraction
- Subtract this power of 2 from the fraction
- Repeat the process until the fraction becomes zero or negligible
- The binary equivalent is formed by concatenating the powers of 2 in the order they were used
- Each step represents a digit in the binary representation (e.g., using 1/2, 1/4, 1/8, 1/16, etc.).
Examples
- Examples of decimal-to-binary conversions are provided using both the multiplication and subtraction methods
- Specific examples are shown for values like 0.25, 0.625, and 18.625 to demonstrate the conversion process.
