    Im having problems trying to compile with gcc. When compiling I get a
    linker error which says "undefined reference to floor".

    My programme looks like this:

    #include <stdio.h>
    #include <math.h>

    int main(int argc, char *argv[]) {
            double mcp1(double n, double m);
            printf("%f\n", mcp1(3.0, 1000.0) + mcp1(5.0, 1000.0));
            return 0;
    }

    double mcp1(double n, double m) {
            double floor(double x);
            return (m * (floor(m/n) + 1.0)) / 2.0;
    }

    It's purpose is to sum all natural multiples of 3 and 5 up to 1000.

    Thanks in advance
