When yade uses high-precision number as Real type the usual (old) import minieigen has to be replaced with:

import yade.minieigenHP as minieigen


This command ensures backward compatibility between both because this module contains only these four lines:

if(yade.config.highPrecisionBits != 64):

Please note that such precision can be very arbitrary, because cpp_bin_float or mpfr take it as a compile-time argument. Hence such minieigenHP cannot be separately precompiled as a package. Though it could be precompiled for some special types such as boost::multiprecision::float128.
