math

The math module provides common numeric and floating-point operations.

Functions that work on any numeric type are generic over the Num(a) context; int and float are its built-in instances, so these functions accept either without conversion. Functions that only make sense for floating-point values take float directly.

abs

math.abs: [Num(a)] a -> a

math.abs(-42)
-- 42

---

min

math.min: [Num(a)] (a, a) -> a

math.min(3, 7)
-- 3

---

max

math.max: [Num(a)] (a, a) -> a

math.max(3, 7)
-- 7

---

clamp

math.clamp: [Num(a)] (a, min: a, max: a) -> a

math.clamp(120, min = 0, max = 100)
-- 100

---

sqrt

math.sqrt: float -> float

math.sqrt(81.0)
-- 9.0

---

pow

math.pow: [Num(a)] (a, int) -> a

math.pow(2, 8)
-- 256

---

floor

math.floor: float -> int

math.floor(3.9)
-- 3

---

ceil

math.ceil: float -> int

math.ceil(3.1)
-- 4

---

round

math.round: float -> int

math.round(3.5)
-- 4
