StdLib for computing Speedometer score In order to compute the geometric mean we need ln and exp SQL functions. This patch also adds those. SQLite would provide those if we were to compile SQLite with -DSQLITE_ENABLE_MATH_FUNCTIONS. But we can't do this because we also need to run using SQLite libraries we have not compiles ourselves (Chrome, Android) and some of those do not support these functinos.
