) => 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,
obj: Float16Array,
) => 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,
obj: Float16Array,
) => boolean,
thisArg?: any,
): number

Returns the index of the first 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.

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,

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(): Float16Array

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(predicate: (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.

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.

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>
