FAQ
About Decimal Fraction Base Conversion
- •Decimal fraction base conversion converts both integer and fractional parts between different bases. Example: FF.8 (hex) = 255.5 (decimal)
- •Fractional conversion principle: Each digit value is multiplied by negative powers of the base (base⁻¹, base⁻², ...) and summed.
- •Some fractions become repeating decimals in certain bases (e.g., 0.1₁₀ = 0.0001100110011...₂). This tool allows precision control to limit digits.
- •Use cases: Understanding floating-point internal representation, color opacity (alpha channel), network protocol data analysis, and more.
- •This tool uses the bignumber.js library to avoid JavaScript's floating-point precision issues.
