XlCalcNet2 is an addon for the XlCalcNet library. It is licensed under the LGPL-3.0 and is therefore provided in a separate repository. It is based on Boost Math, Boost Multiprecision, Boost Odeint, Eigen, GMP, MPFR, MPC and FLINT and provides functions for the same data types as XlCalcNet and also in arbitrary precision.
The manual is the same as for XlCalcNet and is available online in HTML format: XlCalcNet.html. The part which is specific for XlCalcNet2 starts here.
XlCalcNet2 references XlCalcNet and needs to be installed after XlCalcNet has already been successfully installed.
