3Order

Put the learning moves in the order that makes the concept easiest to apply.

The max( x , y ) function can be used to find the highest value of x and y :

C++ has many functions that allows you to perform mathematical tasks on numbers.

C++ <cmath> Library

C++ has many functions that allows you to perform mathematical tasks on numbers.

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);

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);
