Assembly data types limits and examples -


i'm taking assembly language class , book gives me list of data types:

  • byte - 8 bit unsigned integer
  • sbyte - 8 bit signed integer
  • word - 16 bit unsigned integer
  • sword - 16 bit signed integer
  • dword - 32 bit unsigned integer
  • sdword - 32 bit signed integer
  • fword - 48 bit integer
  • qword - 64 bit integer
  • tbyte - 80 bit (10 byte) integer
  • real4 - 32 bit (4 byte) short real
  • real8 - 64 bit (8 byte) long real
  • real10 - 80 bit (10 byte) extended real

just title says, i'm hoping information on upper/lower limits of each of these data types, , maybe examples.

limit of unsigned type:

0 2^bit_count - 1

limit of signed type:

-(2^(bit_count-1)) (2^(bit_count-1))-1

for example, unsigned byte's limit is:

0 255

and signed word's limit is:

-32768 32767

i'm not entirely sure real numbers are, assumption floating point numbers.

for more info, see here.
