Binary Fraction to Decimal Formula:
From: | To: |
Binary fraction to decimal conversion is the process of converting fractional numbers represented in binary (base-2) system to their equivalent decimal (base-10) representation. This is essential in computer science and digital systems where binary fractions are commonly used.
The calculator uses the binary fraction formula:
Where:
Explanation: Each binary digit after the point represents a negative power of two, starting from 2-1 (0.5), 2-2 (0.25), 2-3 (0.125), etc.
Details: Understanding binary fractions is crucial in computer science, digital electronics, and programming. Many floating-point numbers in computers are stored using binary fractions, and conversion helps in debugging and understanding precision issues.
Tips: Enter binary digits (0 or 1) for each position. The calculator supports up to three binary fraction digits (to 1/8 precision). For more digits, you would extend the pattern (adding b4/16, b5/32, etc.).
Q1: Why use binary fractions?
A: Binary fractions are fundamental to how computers represent and process fractional numbers, especially in floating-point arithmetic.
Q2: How accurate is binary fraction representation?
A: Some decimal fractions can't be represented exactly in binary (like 0.1 in decimal), leading to rounding errors in computations.
Q3: What's the relationship to floating-point numbers?
A: Floating-point numbers in computers use binary fractions in their significand (mantissa) along with an exponent.
Q4: Can I convert decimal fractions back to binary?
A: Yes, by repeatedly multiplying the fractional part by 2 and recording the integer parts of the result.
Q5: How many bits are needed for accurate representation?
A: It depends on the required precision. More bits allow for more accurate representation of decimal fractions.
