type casting of minortickmarkCount from int to double

Based on this documentation, minortickmarkCount is int type. Hence, may I know how can we do a minortickmarkCount which is double type?

For example, the stepsize is 1 and the desirable minortickmarkCount is 4, how can we show the minor tick mark count for this condition?
