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.
Function
Definition
math.abs(x)
Returns the absolute value of the argument x.
math.acos(x)
Returns the principal value of the trigonometric arc cosine function
of x.
math.asin(x)
Returns the principal value of the trigonometric arc sine function of
x.
math.atan(x)
Returns the principal value of the trigonometric arc tangent
function of x.
math.atan2(y,x)
Returns the principal value of the trigonometric arc tangent
function of y/x.
math.ceil(x)
Returns the smallest floating-point number not less than x whose
value is an exact mathematical integer.
math.cos(x)
Returns the trigonometric cosine function of x.
math.deg(x)
Returns the value of x in degrees, where x is in radians.
math.exp(x)
Returns the exponential function of x; that is, e
x
, where e is the
base of the natural logarithms.
math.floor(x)
Returns the largest floating-point number not greater than x
whose value is an exact mathematical integer.
math.log(x)
Returns the natural logarithm function of x.
math.log10(x)
Returns the base-10 logarithm function of x.
math.max(x, y, …)
Returns the maximum value of its numeric argument(s).
math.min(x, y, …)
Returns the minimum value of its argument(s).
math.mod(x, y)
Returns an approximation to the mathematical value f such that f
has the same sign as x, the absolute value of f is less than the
absolute value of y, and there exists an integer k such that
k*y+f = x.
math.pi
Variable containing the value of (3.141592654).
math.pow(x, y)
Returns xy.
math.rad(x)
Returns the value of x in radians, where x is in degrees.

Returns the trigonometric sine function of x.
math.sqrt(x)
Returns the non-negative square root of x.
math.tan(x)
Returns the trigonometric tangent function of x.
