Std\FloatArray

Contiguous unboxed array of Float (64-bit double) values. No per-element reference counting. O(1) random access, cache-friendly iteration.

Functions

alloc

alloc : Int -> FloatArray

Allocate an uninitialized FloatArray with the given number of elements.

fill

fill : Int -> Float -> FloatArray

Create a FloatArray of n elements, all set to the given value.

import fill from Std\FloatArray in
fill 1000 0.0   -- 1000 zeros

length

length : FloatArray -> Int

O(1) element count.

get

get : FloatArray -> Int -> Float

O(1) indexed access.

set

set : FloatArray -> Int -> Float -> FloatArray

Persistent set — returns a new array with the element replaced.

head

head : FloatArray -> Float

First element. O(1).

tail

tail : FloatArray -> FloatArray

All elements except the first.

cons

cons : Float -> FloatArray -> FloatArray

Prepend an element.

join

join : FloatArray -> FloatArray -> FloatArray

Concatenate two arrays.

map

map : (Float -> Float) -> FloatArray -> FloatArray

Apply a function to each element. SIMD-eligible for simple operations.

foldl

foldl : (Float -> Float -> Float) -> Float -> FloatArray -> Float

Left fold over all elements.

import fill, foldl from Std\FloatArray in
foldl (\acc x -> acc + x) 0.0 (fill 100 1.5)   -- 150.0
