liudr:
The log function seems to be missing from the arduino reference page but if you use log, it compiles just fine meaning it should be on the reference page. Could the Arduino folks add this to the reference? My students are trying to use thermistors and they need this to calculate for temperature. So some of them pointed out arduino didn't have log on the reference page. I told them to include math.h but it turned out to be unnecessary.
It's part of the AVR standard C library: AVR Libc Home Page
Guess how many other functions are "missing"...
You would do better to point your students at this resource, rather than having the Arduino reference updated (if any update is needed, it should be one that points to the AVR libc link)...
