Functions
math.abs(v: number): number
- Absolute value of v.
math.acos(v: number): number
- Arc cosine of v. (Inverse operation of math.cos (v)).
math.asin(v: number): number
- Arc sine of v. (Inverse operation of math.sin(v)).
math.atan(v: number): number
- Arc tangent of v. (Inverse operation of math.tan (v)).
math.atan2(v1: number, v2: number): number
- Arc tangent of v1/v2.
math.ceil(v: number): number
- Smallest integer >= v
math.cos(v: number): number
- Cosine of v radians.
math.cosh(v: number): number
- Hyperbolic cosine of v radians.
math.deg(v: number): number
- Convert v from radians to degrees. Note that math.rad is the inverse operation.
math.exp(v: number): number
- Compute e to the power v. Note that math.log is the inverse operation.
math.floor(v: number): number
- Largest integer <= v
math.fmod(v1: number, v2: number): number
- The modulus (remainder) of doing: v1 / v2
math.frexp(v: number): number, number
- The frexp function breaks down the floating-point value (v) into a mantissa (m) and an exponent (n), such that the absolute value of m is greater than or equal to 0.5 and less than 1.0, and v = m * 2^n.
math.huge: number
- The value HUGE_VAL, a value larger than or equal to any other numerical value.
- Note that this is a number, not a function.
math.ldexp(m: number, n: number): number
- The ldexp function returns the value of m * 2^n.
math.log(v: number): number
- Natural log of v (that is, to the base e).
math.log10(v: number): number
- Log to the base 10 of v.
math.max(...: number): number
- The highest of one or more numbers.
math.min(...: number): number
- The lowest of one or more numbers.
math.modf(v: number): number, number
- Returns two numbers, the integral part of v and the fractional part of v
math.pi: number
- A variable representing the value of pi (not a function).
math.pow(v1: number, v2: number): number
- v1 raised to the power v2.
math.rad(v: number): number
- Convert v from degrees to radians.
math.random(n?: number, u?: number): number
- With no arguments, returns a random number in the range [0, 1]. That is, zero up to but excluding 1.
- With 1 argument, returns an integer in the range [1, n]. That is from 1 up to and including n.
- With 2 arguments, returns an integer in the range [n, u]. That is from n up to and including u.
- Use
math.randomseed(n: number)to seed the generator.
math.randomseed(n: number)
- Seeds the random number generator with an integer.
- Re-seed with the same number to regenerate the same sequences by calling math.random.
- Seeding with os.time () is a common technique to make random numbers different each time.
math.sin(v: number): number
- Sine of v radians.
math.sinh(v: number): number
- Hyperbolic sine of v radians.
math.sqrt(v: number): number
- Square root of v.
math.tan(v: number): number
- Tangent of v radians.
math.tanh(v: number): number
- Hyperbolic tangent of v radians.
