Units and numerical precision

Quantas distinguishes between stored numerical precision and display precision.

Stored values

Native calculations and HDF5 persistence use:

• float64 for real values;

• complex128 for complex values.

There is no runtime precision selector for scientific calculations.

Displayed values

Formatting and display precision belong to report and plot renderers. They do not change the stored data.

Workflow pages document the scientific units relevant to each module. Where possible, units are also stored explicitly in metadata associated with results, reports, or exported tables.
