Detailed Description

Interact with a uniform grid of increasing values.

This simple class is used by physics vectors and classes that need to do lookups on a uniform grid.

CELER_FUNCTION size_type celeritas::UniformGrid::find ( value_type  value ) const

inline

Find the value bin such that data[result] <= value < data[result + 1].

The given value must be in range, because out-of-bounds values usually require different treatment (e.g. clipping to the boundary values rather than interpolating). It's easier to test the exceptional cases (final grid point) outside of the grid view.
