C++ has many functions that allows you to perform mathematical tasks on numbers.
Max and min
The max( x , y ) function can be used to find the highest value of x and y :
Example
cout << max(5, 10);And the min( x , y ) function can be used to find the lowest value of x and y :
Example
cout << min(5, 10);C++ <cmath> Library
Other functions, such as sqrt (square root), round (rounds a number) and log (natural logarithm), can be found in the <cmath> header file:
Example
// Include the cmath library #include <cmath> cout << sqrt(64); cout << round(2.6); cout << log(2);
