Math library functions
This library is an interface to most of the functions of the ANSI C math library. All trigonometric
functions work in radians. The functions math.deg() and math.rad() convert between radians
and degrees.

Description
Returns the absolute value of x.
Returns the arc cosine of x.
Returns the arc sine of x.
Returns the arc tangent of x.
Returns the arc tangent of y/x, but uses the signs of both parameters to find
the quadrant of the result. (It also handles correctly the case of x being zero.)
Returns the smallest integer larger than or equal to x.
Returns the cosine of x.
Returns the angle x (given in radians) in degrees.
x
Returns the value e .
Returns the largest integer smaller than or equal to x.
Returns m and e such that x = m2
value of m is in the range [0.5, 1] (or zero when x is zero).
e
Returns m2 (e should be an integer).
Returns the natural logarithm of x.
Returns the base-10 logarithm of x.
Returns the maximum value among its arguments.
Returns the minimum value among its arguments.
The value of π (3.141592654).
y
Returns x . (You can also use the expression x^y to compute this value.)
Returns the angle x (given in degrees) in radians.
This function is an interface to the simple pseudo-random generator function
rand provided by ANSI C.
When called without arguments, returns a uniform pseudo-random real
number in the range [0,1]. When called with an integer number m,
math.random returns a uniform pseudo-random integer in the range [1, m].
When called with two integer numbers m and n, math.random returns a
uniform pseudo-random integer in the range [m, n].
Sets x as the "seed" for the pseudo-random generator: equal seeds produce
equal sequences of numbers.
Returns the trigonometric sine function of x.
Returns the square root of x. (You can also use the expression x^0.5 to
compute this value.)
Returns the tangent of x.
