element-wise math ¶

function numluau.abs(
    Array : types.ndArray<number>
) : types.ndArray<number>

The element-wise math functions apply one Luau math function to every value in an ndArray<number> and return the result as a new ndArray<number>.

Supported functions¶

The following wrappers are available:

abs, acos, asin, atan, ceil, cos, cosh, deg, exp, floor, log, log10, modf, rad, round, sign, sin, sinh, sqrt, tan, and tanh.

log2 is also available and applies math.log(value, 2) to each item.

Parameters¶

Array : ndArray <number>

The numeric array the function is applied to.

Returns -> ndArray <number>

A new ndArray<number> containing the element-wise result. The input array is copied before values are transformed.

Example¶

local numluau = require("path.to.numluau")

local input = numluau.array({-2.7, -0.5, 0, 1.2, 3.9})

local absolute = numluau.abs(input)
local rounded = numluau.round(input)

print(absolute) -- array([2.7 0.5 0 1.2 3.9])
print(rounded) -- array([-3 -1 0 1 4])
