Im trying to program a money counting fuction in C++, but I can't figure out how to do it. I want it to count long integers using this range: 5 - 1,000,000. Any ideas? (no floats or doubles) Just bills like 5,10,15,20-50,55-80, you know! Im a beginner programmer, please help.

long maximumCash=1000000;
long minimumCash=5;

How much math am I needed?

Try this. It is easy to understand. I wrote it years ago in procedural
C. It converts global currencies.

You would want to change the setprecision function
for each currency correctness. See US for example.

Some currencies around the world use 4 decimal places.
