Post your code - we'll take a look.

oh and by the way - are you sure you have a problem? The result seems to be very close to correct one:

std::cout.precision(int);

to set the precision of floats, doubles, and long doubles.

Also, the integral seems correct, Integral(x⁻¹ dx)[10, 1] = ln(x)[10] - ln(x)[1] = ln(10) = 2.302585093
Since ln(1) = 0.

Good advice.

Actually it seems that OP does not have a problem with existing code, but just want some code be written for him.

I knew somebody was going to mention that. I assumed that he had a C routine that calculated the integral. From this routine he would fetch the return value. Since this is a C++ forum, he'd most likely output it using std::cout, considering his C code doesn't seem to be wrong.
