Calculator for radix conversion of numerals

Build

Assemble with the Netwide Assembler (NASM) and link with gcc.

nasm -f elf64 calc.asm && gcc calc.o -o calc.out

Run

./calc.out

Enter a number of radix 2, 8, 10 or 16, i.e. binary, octal, decimal or hexdecimal. The acceptable range is [0, 2^32-1], i.e. 32-bit unsigned integers.

Format for each radix:

• binary: 0bddd...
• octal: 0ddd...
• decimal: ddd...
• hexdecimal: 0xddd... (case insensitive)

"ddd..." represents digits. Example for each:

• binary: 0b1011011110011011010
• octal: 01336332
• decimal: 376026
• hex: 0x5bcda or 0x5BCDA

Enter "q" to quit.
