Float64Array()

The Float64Array() typed array constructor creates a new Float64Array object, which is, 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).

Syntax​

new Float64Array()
new Float64Array(length)
new Float64Array(typedArray)
new Float64Array(object)

new Float64Array(buffer)
new Float64Array(buffer, byteOffset)
new Float64Array(buffer, byteOffset, length)

Note: Float64Array() can only be constructed with new. Attempting to call it without new throws a TypeError.
