Example code : Illustrate use of Infinity
var
float1, float2 : single;
begin
float1 := Infinity;
float2 := 23;
ShowMessage('float1 = '+FloatToStr(float1));
ShowMessage('float2 = '+FloatToStr(float2));
ShowMessage('float1 - float2 = '+FloatToStr(float1 - float2));
ShowMessage('-float1 = '+FloatToStr(-float1));
end;
