Number Systems Calculators — Mathematics
Move between number bases and machine representations with confidence. The binary-to-decimal, hex-to-decimal, and octal converters translate values across bases, the two’s complement calculator shows how signed integers are stored, and the ASCII and XOR tools map characters to codes and perform bitwise logic. Each displays the conversion steps, making them study aids for computer science, digital logic, and low-level programming.
