Common Mathematical Functions <cmath>
The <cmath> header defines an extensive collection of common math functions in the std namespace. Unless otherwise specified, all functions are overloaded to accept all standard numerical types, with the following rules for determining the return type:
If all arguments are float, the return type is float as well. Analogous for double and long double inputs.
If mixed types or integers are passed, these numbers are converted to double, and a double is returned as ...
