value of (atan y ) is a number between -pi/2 and pi/2 (exclusive) whose tangent is y . If the optional second argument x is given, the value of (atan y x) is the angle in radians between the vector [ x , y ] and the X axis. <span>Function: exp arg This is the exponential function; it returns e to the power arg . Function: log arg &optional base This function returns the logarithm of arg , with base base . If you donâ€™t specify base , the natural base e is used. If arg or base is ne
