◆ sqrt_tol()

CELER_CONSTEXPR_FUNCTION real_type celeritas::sqrt_tol ( )

Square root of the soft equivalence tolerance for Celeritas.

This tolerance is needed for operations where the accuracy is limited by the square root of machine precision.

Todo:: Move orange tolerance and related operations into corecel/math alongside this, revisit ArrayUtils soft comparisons.
