interface Float16Array
import { type Float16Array } from "https://deno.land/x/float16@v3.8.7/mod.ts";

A typed array of 16-bit float values. The contents are initialized to 0. If the requested number of bytes could not be allocated an exception is raised.

Index Signatures

[index: number]: number

Properties

readonly
BYTES_PER_ELEMENT: number

The size in bytes of each element in the array.

readonly
buffer: ArrayBufferLike

The ArrayBuffer instance referenced by the array.

readonly
byteLength: number

The length in bytes of the array.

readonly
byteOffset: number

The offset in bytes of the array.

readonly
length: number

The length of the array.

readonly
[[Symbol.toStringTag]]: "Float16Array"

Methods

[[Symbol.iterator]](): IterableIterator<number>
entries(): IterableIterator<[number, number]>

Returns an array of key, value pairs for every entry in the array

keys(): IterableIterator<number>

Returns an list of keys in the array

values(): IterableIterator<number>

Returns an list of values in the array

at(index: number): number | undefined

Returns the item located at the specified index.

copyWithin(
target: number,
start: number,
end?: number,
): this

Returns the this object after copying a section of the array identified by start and end to the same array starting at position target

every(callbackfn: (
value: number,
index: number,
array: Float16Array,
) => unknown, thisArg?: any): boolean

Determines whether all the members of an array satisfy the specified test.

fill(
value: number,
start?: number,
end?: number,
): this

Returns the this object after filling the section identified by start and end with value

filter(predicate: (
value: number,
index: number,
array: Float16Array,
) => any, thisArg?: any): Float16Array

Returns the elements of an array that meet the condition specified in a callback function.

find(predicate: (
value: number,
index: number,
) => boolean, thisArg?: any): number | undefined

Returns the value of the first element in the array where predicate is true, and undefined otherwise.

findIndex(predicate: (
value: number,
index: number,
) => boolean, thisArg?: any): number

Returns the index of the first element in the array where predicate is true, and -1 otherwise.

findLast(predicate: (
value: number,
index: number,
) => boolean, thisArg?: any): number | undefined

Returns the value of the last element in the array where predicate is true, and undefined otherwise.

findLastIndex(predicate: (
value: number,
index: number,
) => boolean, thisArg?: any): number

Returns the index of the last element in the array where predicate is true, and -1 otherwise.

forEach(callbackfn: (
value: number,
index: number,
array: Float16Array,
) => void, thisArg?: any): void

Performs the specified action for each element in an array.

includes(searchElement: number, fromIndex?: number): boolean

Determines whether an array includes a certain element, returning true or false as appropriate.

indexOf(searchElement: number, fromIndex?: number): number

Returns the index of the first occurrence of a value in an array.

join(separator?: string): string

Adds all the elements of an array separated by the specified separator string.

lastIndexOf(searchElement: number, fromIndex?: number): number

Returns the index of the last occurrence of a value in an array.

map(callbackfn: (
value: number,
index: number,
array: Float16Array,
) => number, thisArg?: any): Float16Array

Calls a defined callback function on each element of an array, and returns an array that contains the results.

reduce(callbackfn: (
previousValue: number,
currentValue: number,
currentIndex: number,
array: Float16Array,
) => number): number

Calls the specified callback function for all the elements in an array. The return value of the callback function is the accumulated result, and is provided as an argument in the next call to the callback function.

reduce(callbackfn: (
previousValue: number,
currentValue: number,
currentIndex: number,
array: Float16Array,
) => number, initialValue: number): number
reduce<U>(callbackfn: (
previousValue: U,
currentValue: number,
currentIndex: number,
array: Float16Array,
) => U, initialValue: U): U
reduceRight(callbackfn: (
previousValue: number,
currentValue: number,
currentIndex: number,
array: Float16Array,
) => number): number

Calls the specified callback function for all the elements in an array, in descending order. The return value of the callback function is the accumulated result, and is provided as an argument in the next call to the callback function.

reduceRight(callbackfn: (
previousValue: number,
currentValue: number,
currentIndex: number,
array: Float16Array,
) => number, initialValue: number): number
reduceRight<U>(callbackfn: (
previousValue: U,
currentValue: number,
currentIndex: number,
array: Float16Array,
) => U, initialValue: U): U
reverse(): this

Reverses the elements in an Array.

set(array: ArrayLike<number>, offset?: number): void

Sets a value or an array of values.

slice(start?: number, end?: number): Float16Array

Returns a section of an array.

some(callbackfn: (
value: number,
index: number,
array: Float16Array,
) => unknown, thisArg?: any): boolean

Determines whether the specified callback function returns true for any element of an array.

sort(compareFn?: (a: number, b: number) => number): this

Sorts an array.

subarray(begin?: number, end?: number): Float16Array

Gets a new Float16Array view of the ArrayBuffer store for this array, referencing the elements at begin, inclusive, up to end, exclusive.

toReversed(): Float16Array

Copies the array and returns the copy with the elements in reverse order.

toSorted(compareFn?: (a: number, b: number) => number): Float16Array

Copies and sorts the array.

with(index: number, value: number): Float16Array

toLocaleString(): string

Converts a number to a string by using the current locale.

toString(): string

Returns a string representation of an array.

valueOf(): Float16Array

Returns the primitive value of the specified object.
