Finite resolution turns a displayed value into a checked interval. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
A reported bin has endpoints
Resolution 2 gives half-width 1. Center 14 means interval 13 through 15.
[13,15]
Separated bins support a separated claim
A second center at 18 gives interval 17 through 19. These intervals are separated in this training model.
