Upgrading from:

NumericalMath`Approximations`

All the functionality of NumericalMath`Approximations` is now available in the newly created Function Approximations Package.

To access functionality from the new Function Approximations Package, load FunctionApproximations`:

Version 5.2 << NumericalMath`Approximations`; RationalInterpolation[Exp[x], {x, 2, 4}, {0, 1/3, 2/3, 1, 4/3, 5/3, 2}]
Wolfram Language code: <<FunctionApproximations`; RationalInterpolation[Exp[x], {x, 2, 4}, {0, 1 / 3, 2 / 3, 1, 4 / 3, 5 / 3, 2}]
