stdout.put outputs integers in decimal format stdout.put outputs registers, bytes, words, dwords in hex format stdin.get's input base is hex for those same 'types', but will expect decimal format if its argument is of an integer type.

If you want to display a value in decimal format but it's stored in a register, use stdout.puti32 (or ...i16 etc).

If you want to use a decimal base when storing an input to a register, byte, word, etc., use stdin.geti32 etc.

If you want to use a hex base when storing an input to an integer type, use stdin.geth32 etc. For output, stdout.puth32 etc.

Sign Extension

• cbw() = "convert byte in AL to word in AX"
• cwd() = "convert word in AX to doubleword in DX:AX"
• cdq() = "convert doubleword in EAX to quadword in EDX:EAX"
• cwde() = "convert word in AX to doubleword in EAX"
• movsx(source: memory address OR register, dest: register) = convert byte/word/doubleword in source to word/doubleword/quadword in dest (dest must be larger than source)
• movzx(source, dest) works the same as movesx for zero extension
• to zero extend values in 8-bit registers, just zero out their complementary high-order register:
  • AL -> AH, BL -> BH, etc.
