Reduced testcase:
double bessel_Kn_scaled_small_x(int n, double x)
{
int k;
double y = 0.25 * x * x;
double ex = exp(x);
double k_term;
double term1, sum1, ln_pre1;
double term2, sum2, pre2;
for(k=1; k<=n-1; k++)
{
k_term *= -y/(k * (n-k));
sum1 += k_term;
}
term1 = 0.5 * exp(ln_pre1) * sum1;
return ex * (term1 + term2);
}
