more accuracy in C++

January 5, 2003, 02:12

Hi, there,

How are you doing?

These days I have difficult in the numerical computations. As you know there are the single, double and more accuracy precision in the Fortran. When we are using the C++, it seems that there are only float and double. Is there any way to improve the accuracy during the computation using the C++?

Thank you very much.

There's "long double" type for extented precision.

Although true in most cases, the C++ standard does not REQUIRE long double to be any longer than an ordinary double. Use it at your peril.
