TIntegerHelper.Bits

Read or write a bit

Declaration

Source position: syshelph.inc line 728

public property TIntegerHelper.Bits[aIndex: TIntegerBitIndex] : Boolean
  read GetBit
  write PutBit;

Description

Bits property reads or writes boolean value to a bit number determined by argument aIndex.

MyInteger.Clear;// %00000000000000000000000000000000 MyInteger equals 0
MyInteger.Bits[0] := true;  // %00000000000000000000000000000001 MyInteger equals 1
MyInteger.Bits[2] := true;  // %00000000000000000000000000000101 MyInteger equals 5
WriteLn(MyInteger.Bits[2]); // TRUE
