Function Documentation

decimal_to_binary()

int decimal_to_binary

(

unsigned int

number

)

Decimal to binary using recursion algorithm.

For example, if number = 5, the function returns the decimal integer 101.

Parameters

number

positive integer number to convert

Returns

integer with digits representing binary value representation of number.

{
    return number == 0 ? 0 : number % 2 + 10 * decimal_to_binary(number / 2);
}

test()

test

(

)

Test function.

A function to test the kMeans function Generates 100000 points in a circle of radius 20.0 with center at (0,0) and cluster them into 5 clusters

{
    const int sets[][2] = {
        {0, 0}, {1, 1}, {2, 10}, {3, 11}, {4, 100}, {6, 110}, {7, 111},
        /* add more data sets to test */
    };
 
    for (int i = 0, size = sizeof(sets) / sizeof(sets[0]); i < size; ++i)
    {
        assert(decimal_to_binary(sets[i][0]) == sets[i][1]);
    }
