rc­col – Dec­i­mal-cen­tered op­tion­ally rounded num­bers in tab­u­lar

The rc­col pack­age pro­vides dec­i­mal-cen­tered num­bers: cor­re­spond­ing dig­its and dec­i­mal sep­a­ra­tors aligned. Fur­ther­more, round­ing to the de­sired pre­ci­sion is pos­si­ble.
The pack­age makes use of the flt­point pack­age (as well as the LaTeX re­quired ar­ray pack­age).
