I implemented a function [0] which computes the logarithm in base two of integers and want to know what naming is most

appropriated:

ilog2

or simply

log2

My instinct is for log2 so it might be specialised for floating point too.

log2 conflicts with the C++0x library which works with floating point
(and returns a double when it's given an integer).

This is the point.

Also, does the function compute floor(log2(x)) or ceil(log2(x))?

floor(log2(x))
