C++ Math
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:
And the min(x,y) function can be used to find the lowest value of
x
and y:
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);
