SCAR Code:
program L337Calculator;
const
Question = 664*2+4/2+2*7/3+2.9+0.099999999999;
begin
ClearDeBug;
if Question = 1337 then
begin
Writeln('LEET Calculator Made by ZYTEX');
Writeln(FloatToStr(Question));
end else
Writeln(FloatToStr(Question));
end.
As you can see: The program will print out 'LEET Calculator Made by ZYTEX' if the answer is 1337, but now it only prints out 1337.. 
EDIT: Add 1 more '9' to the Question and then it will print 'LEET Calculator Made by ZYTEX'
EDIT2: Make the Question this: 664*2+4/2+2.0*7/3+2.9+0.099999999999; I only added '.0' It prints out '1337,66666666667'...
