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.
