You and a friend walk into a bar. The bartender treats you well, so you decide to tip him. So you pull out your trusty pocket computer and write a quick program to calculate a tip for you since it has no built in calculator. But wait! Your operator keys are broken! Your task is to calculate a 20% tip for any given input amount. The test inputs will be in the form of xx.xx e.g. 20.96. Here are the rules:
- No use of the following in mathematical form operators:
+ - * / %(Thanks Wally West)
- No use of built in percent functions or APIs
- No accessing the network
- No use of
- No Windows Calculator (yes people have answered with it before)
- No built in tip functions (Not that any language would have one)
Output should be rounded up to two decimal places.
Score is based on length in bytes.
-20% if your program can accept any tip amount. Input for amount will be given in the form of xx e.g. 35 not 0.35
