 As far as we are aware, the only alternative package to CRlibm is [MPFR](http://www.mpfr.org/), which provides correctly-rounded functions for
 floating-point numbers of **arbitrary precision**, including the power function. However, it can be slow.
 
-MPFR is wrapped in base Julia in the `BigFloat` type, and can emulate double-precision floating point by setting the precision to 53 bits.

 The function `CRlibm.shadow_MPFR()` can be called to redefine the functions that take floating-point arguments to also use the MPFR versions; this is automatic if the `CRlibm` library is not available.
