I believe you are allowed to 'roll up' to the next higher value standard size per 430.52(C)(1) Exception 1:
Exception No. 1: Where the values for branch-circuit short-circuit and ground-fault protective devices determined
by Table 430.52 do not correspond to the standard sizes or ratings of fuses, nonadjustable circuit breakers,thermal protective devices, or possible settings of adjustable circuit breakers, a higher size, rating, or possible setting that does not exceed the next higher standard ampere
rating shall be permitted.
