root

Calculate the n-th root of a number

root<return_type>(n, a);

will return the n-th root (index/degree) of a number (radicand). The return_type specifies in which data type the result will be returned in, like shown in below example:

root<int>(3, -34); //-3
root<float>(5, 23123); //7.4612
root<bool>(3, -15); //1
------------------------
root<char>(15, 98756); //'ß'

The n-th root of a number is undefined for n (index/degree) being an even number and a (radicand) being an non-positive number. As a result, the compiler will throw the following exception:

Error: The nth root function is undefined for non-positive values of even root indexes (degrees)
