nbaseprt – Print num­bers in non-dec­i­mal bases

The pack­age nbaseprt prints in­te­ger num­bers in dif­fer­ent bases (oc­tal, dec­i­mal, hex­adec­i­mal, bi­nary) sim­i­larly to the numprint pack­age. But here, the num­ber of dig­its within one group de­pends on the base.
This is a beta ver­sion of nbaseprt.sty. The main com­mand \nbaseprint will stay sta­ble but all con­fig­u­ra­tion com­mands and the out­put of \nbaseprint may change in fu­ture. Please give me feed­back what can be im­proved and if the ab­bre­vi­a­tions for the dif­fer­ent num­ber bases are cor­rect.
