math.log (x [, base]) Returns the logarithm of x in the given base. The default for base is e (so that the function returns the natural logarithm of x).

math.huge The float value HUGE_VAL, a value larger than any other numeric value.

math.fmod (x, y) Returns the remainder of the division of x by y that rounds the quotient towards zero. (integer/float)

math.floor (x) Returns the largest integral value smaller than or equal to x.

math.exp (x) Returns the value ex (where e is the base of natural logarithms).

math.deg (x) Converts the angle x from radians to degrees.

math.cos (x) Returns the cosine of x (assumed to be in radians).

math.ceil (x) Returns the smallest integral value larger than or equal to x.

math.atan (y [, x]) Returns the arc tangent of y/x (in radians), but uses the signs of both parameters to find the quadrant of the result. (It also handles correctly the case of x being zero.) The default value for x is 1, so that the call math.atan(y) returns the arc tangent of y.

math.asin (x) Returns the arc sine of x (in radians).
