Float32Array Interface

The Float32Array type represents an array of 32-bit floating point numbers (corresponding to the C float data type).

Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

Extends

ArrayBufferView, List<E>

Constructors

Code new Float32Array(int length) #

Float32Array(int length);

Code new Float32Array.fromBuffer(ArrayBuffer buffer, [int byteOffset, int length]) #

Float32Array.fromBuffer(ArrayBuffer buffer, [int byteOffset, int length]);

Code new Float32Array.fromList(List list) #

Float32Array.fromList(List<num> list);

Static Fields

Code final int BYTES_PER_ELEMENT #

static final int BYTES_PER_ELEMENT = 4;

Methods

Code void setElements(Object array, [int offset]) #

void setElements(Object array, [int offset]);

Code Float32Array subarray(int start, [int end]) #

Returns a new Float32Array view on the ArrayBuffer store for this Float32Array object.

Parameters

begin: The offset to the first element in the array to be referenced by the new Float32Array object.
end Optional: The offset to the last element in the array to be referenced by the new Float32Array object; if not specified, all elements from the one specified by begin to the end of the array are included in the new view.

Notes

The range specified by begin and end is clamped to the valid index range for the current array; if the computed length of the new array would be negative, it's clamped to zero. If either begin or end is negative, it refers to an index from the end of the array instead of from the beginning.

Note: Keep in mind that this is creating a new view on the existing buffer; changes to the new object's contents will impact the original object and vice versa.

from MDN

Float32Array subarray(int start, [int end]);

Fields

Code final int length #

The number of entries in the array. Read only.

from MDN

final int length;
