Have a look here for math.h fucntions: http://www.opengroup.org/onlinepubs/007908799/xsh/math.h.html Do a "man function" to find out more about the individual functions. e.g "man log". My guess is that you haven't linked your source code to the math library. (-lm option) i.e gcc -lm myfile.c -o myfile With kind regards, Didier. --- PhD student.
