Here are three converters/calculators I’ve written; you can use them to explore binary numbers:
- Decimal/Binary Converter
An arbitrary-precision, decimal to binary and binary to decimal converter, which converts both integer and fractional values.
- Binary Calculator
An arbitrary-precision binary calculator, which adds, subtracts, multiplies, and divides integer and fractional values.
- Decimal/Two’s Complement Converter
An arbitrary-precision, decimal to two’s complement and two’s complement to decimal converter.
- Decimal to Floating-Point Converter
A decimal to binary floating-point converter, which produces correctly rounded IEEE 754 single-precision and double-precision conversions.
- Base Converter
An arbitrary-precision, number base to number base converter, which converts both integer and fractional values.
