This package provides numeric instances for MPFR that use "Implicit Configurations" from http://www.cs.rutgers.edu/~ccshan/prepose/prepose.pdf to choose a Rounding and Precision. For those that do not want to use reflection, explicit instances are provided for common precisions and for the built-in rounding modes. This package should work correctly with GHC 8.4.4 or later. rounded version 1.x is for MPFR version 4.0 and above.
