  The known approaches of number-phase problem (for a quantum oscillator) are
mutually contradictory. All of them are subsequent in respect with the
Robertson-Schr\"{o}dinger uncertainty relation (RSUR). In oposition here it is
proposed a new approacch aimed to be aboriginal as regard RSRUR. From the new
perspective the Dirac's operators for vibrational number and phase appear as
correct mathematical tools while the alluded problem receives a natural
solution. PACS codes: 03.65.-w, 03.65.Ca, 03.65.Fd, 03.65.Ta Keywords: quantum
oscillator, number and phase, uncertainty relations.
