How it works
Free programmer calculator. Convert between binary, octal, decimal, and hexadecimal with live sync, evaluate expressions with C-like precedence, run bitwise AND, OR, XOR, NOT and shifts, toggle individual bits, and read signed and unsigned 8/16/32/64-bit interpretations plus the ASCII character.
- 01
Enter a value
Type an expression or edit any base field; the other three bases update instantly.
- 02
Pick a width
Choose 8, 16, 32, or 64 bits to see the signed and unsigned interpretations.
- 03
Toggle bits
Click bits in the grid to flip them, or run a bitwise operation on two operands.
