--What is the #include statement for cpp_rational?  I can't manage to find it.

It's right at the top of https://www.boost.org/doc/libs/1_69_0/libs/multiprecision/doc/html/boost_mul... It's all in #include

-When using non-floating point, is there a method to obtain a variable precision pi, or do I have to use

We've been through this before - cpp_rational is an *exact* type, it absolutely does not do irrational numbers, much less transcendental ones.  The clue is in the name. If you need pi, then you need floating point. John. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
