Hi,
In CHICKEN 4.9.0rc1 and 4.10.0 both with numbers 4.6:
-----
#;1> (use numbers)
#;2> (define (log2 n) (/ (log n) (log 2)))
#;3> (= (log2 (expt 2 252)) (ceiling (log2 (expt 2 252))))
#t
#;4> (= (log2 (expt 2 251)) (ceiling (log2 (expt 2 251))))
#f
#;5> (log2 (expt 2 251))
251.0
#;6> (ceiling (log2 (expt 2 251)))
252.0

Is it just late on a Friday? Am I crazy?
Regards,
@ndy
