Number Converters
Converters
Integer → Binary
Convert integers to binary and binary to integers.
Integer ↔ Hexadecimal
Convert integers to hex (and hex back to integers).
Floating Point → Binary (with rounding error)
Exact decimal rational → finite binary expansion; shows rounding/truncation error.
Binary (with point) → Floating Point
Binary fractions to decimal; shows exact value and JS Number rounding gap.
Decimal ↔ IEEE-754 Float32 (Bits/Hex)
Decimal to IEEE-754 single precision, interactive bit toggles, hex view, rounding error.
