>  I am doing a research on D2TCP(http://dl.acm.org/citation.cfm?id=2342388), I just want to implement it into the linux kernel. When calculating the penalty function, it is p = a^d, where 0< a < 1 and  0< d < 1. Since the kernel only offers integer,   so in my code, so I let a multiply 2^10. But I have no idea of calculating a^d when 0< d < 1. May be I want a  approximate algorithm or other methods. Can you help me ?

This is not a linux kernel list, please ask on a proper list...
