Float64Array

js.lib.Float64Array (extern class)
Implements: ArrayBufferView

The Float64Array typed array represents an array of 64-bit floating point numbers (corresponding to the C double data type) in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0. 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).

Static Members

BYTES_PER_ELEMENT: Int

Returns a number value of the element size. 8 in the case of an Float64Array.

Instance Members

BYTES_PER_ELEMENT_: Int

Returns a number value of the element size.

buffer: ArrayBuffer

Returns the ArrayBuffer referenced by the Float64Array Fixed at construction time and thus read only.

byteLength: Int

Returns the length (in bytes) of the Float64Array from the start of its ArrayBuffer. Fixed at construction time and thus read only.

byteOffset: Int

Returns the offset (in bytes) of the Float64Array from the start of its ArrayBuffer. Fixed at construction time and thus read only.

length: Int

Returns the number of elements hold in the Float64Array. Fixed at construction time and thus read only.
