 The basic type of the floating point variables is usually *Float64*, but can be set to any type *FloatType <: AbstractFloat* via\
 *@instantiateModel(..., FloatType = xxx)*, for example it can be set to *Float32, DoubleFloat, Measurement{Float64}, StaticParticles{Float64,100}*.
 
-After a simulation, an instantiated model is treated as a *signal table* and therefore all functions from package [SignalTables.jl](https://github.com/ModiaSim/SignalTables.jl) can be used on it. In particular, the simulation results together with all parameter and start values can be stored on file in *JSON* format with *writeSignalTable(filename, instantiatedModel)* or in *HDF5* format via [JDL](https://github.com/JuliaIO/JLD.jl), see for example the result of a simple test model - [firstOrder.json](https://modiasim.github.io/Modia.jl/resources/fileio/firstOrder.json).
