Is the number base converter free?

Yes! Our number base converter is completely free with no registration required. Convert unlimited numbers between all supported bases at no cost.

What number bases are supported?

We support binary (base 2), octal (base 8), decimal (base 10), hexadecimal (base 16), base 32, and base 36 conversions with full bidirectional support.

Can it handle negative numbers?

Yes! The converter fully supports negative numbers in all bases and provides accurate conversions while maintaining sign information.

What are bitwise operations?

Bitwise operations (AND, OR, XOR, NOT) work on individual bits of numbers. Our tool lets you apply these operations to understand bit manipulation in programming.

What is IEEE 754 representation?

IEEE 754 is the standard for floating-point arithmetic used in computers. Our tool shows how decimal numbers are represented in this format, useful for understanding computer memory storage.

How to Use

Type a number into any field below and every other base updates instantly. Conversions use big-integer math so even 64-bit and larger values stay exact. Invalid digits for a base are flagged. Use the custom base, bit grouping, two's-complement width and bitwise tools for deeper analysis.
