A shortint is a signed integer in the range of -128 to 127. The shortint is 8 bits long.

The Byte type is 8 bits long, too. But the byte datatype is an unsigned type, meaning that it encodes numbers from 0 to 255.

  a_shortint: shortint;
  a_byte : byte;
  s1, s2 : string;
  a_shortint := %11110001;   // binary number
  a_byte     := %11110001;
  s1 := IntToStr(a_shortint); // s1 = '-15'
  s2 := IntToStr(a_byte);     // s2 = '241'
