Decimal numbers in C++

Is there anyway to use decimal numbers in C++?

I don't know that much about number types
(

Code:

double long unsigned (etc.)

so maybe there's just some type I don't know about :confused

 

does float work?

 

yeah float is your answer

eg.
float a = 10;

 

What exactly do you mean by decimal? That is, do you care about the form: actual binary floating-point numbers (like float or double) or something else like BCD or string representation or fixed-decimal? or do you just want to be able to store the number 17.62 or whatever. If you don't care, float is pretty much just a smaller version of double, and either can handle decimal numbers, though double is more precise.
