math.pi
Variable containing the value of π (3.141592654).
math.pow(x, y)
Returns x
y
.
math.rad(x)
Returns the value of x in radians, where x is in degrees.
math.sin(x)
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.
math.frexp()
Splits x into a fraction f and exponent n, such that f is 0.0 or 0.5
<= | f | <= 1.0, and f * 2
n
is equal to x. Both f and n are returned;
f,n = math.frexp(x).
math.ldexp(x, n)
Returns the inverse of the math.frexp() function; it computes the
value
x * 2
n
math.random([x],[y])
When called without an argument, returns a pseudo-random real
number in the range [0, 1).
When called with number x, returns a pseudo-random integer in
the range [1,n].
When called with two arguments, x and y, returns a pseudo-
random integer in the range [x, y].
math.randomseed(x)
Sets a “seed” for the pseudo-random generator. Equal seeds
produce equal sequences of numbers.
