The ln function is done by "log" in gcc and is supported by math.h. The log10 function is done by "log10" in gcc and is supported by math.h. There is a constant M_LOG2E in math.h which is log2 of e. To get log2 of x, this is the same as M_LOG2E*log(x).

Kind persons:
I routinely program using C and compile with gcc. My problem is that I need some math log functions--ln, log10, and log2--and these functions are not included in math.h from what I can determine. Can anyone suggest how I can get these functions?
I have tried notes to the glibc groups and not received any replies.
Thanks.
