代码说明：

一个多精度高效的浮点计算C语言库 , 基于GMP .-The MPFR library is a C library for multiple-precision floating-point computations with correct rounding. MPFR has continuously been supported by the INRIA and the current main authors come from the CACAO and Arénaire project-teams at Loria (Nancy, France) and LIP (Lyon, France) respectively see more on the credit page. MPFR is based on the GMP multiple-precision library.
