Hi
It would be so good if some missing operations on numbers could be
added to the standard set :
For regular integer : sqrt, pow, log2, factorial
For Big_int : log2, lsl, lsr, lor, land, lxor, lnot, factorial
For reals : erf, erfc, gamma, lgamma, and constante pi
For info : log2 n returns the position of the highest weight bit in n
(integer logarithmic)
(log2 0 -> 0, log2 1 -> 1, log2 2 to 3 -> 2, log2 4 to 7 -> 3, log2 8
to 15 -> 4, log2 16 to 31 -> 5, etc...)
The lack of those functions gives a feeling of immaturity of the
language.
Is it possible in some near futur release to add them ?
Christophe
