Hey! I have problem with mpf_div and mpf_get_d. After 0.7/1.0 I will get 0.53. Do you have any suggestion? I am testing in a MacBook Air 64 bit. In iOS Simulator. double ll1 = mpf_get_d(a[i][k]); double ll2 = mpf_get_d(a[k][k]); mpf_div(l, a[i][k], a[k][k]); double ll = mpf_get_d(l); Regards, János
