Arithmatic functions in c++

[bajajv]

Hi,
I have to implement some maths functions.
Just wanted to know that is there any library in c++ which contains arithmatic functions like min, max, average, count, means and deviations?
Or do I need to implement them all?

Depends how you hold your data, the algorithm functional and numeric headers declare functions and templates that can be of use calculating this sort of thing using functors (functional objects). But then tend to work on STL containers.

And of course the is the old c maths library (cmath header) which contains some raw maths functions, trig and exponential).
