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

Constructor
Variables
finalbuffer:ArrayBuffer
Returns the ArrayBuffer referenced by the Float32Array Fixed at construction time and thus read only.
finalbyteLength:Int
Returns the length (in bytes) of the Float32Array from the start of its ArrayBuffer. Fixed at construction time and thus read only.
finalbyteOffset:Int
Returns the offset (in bytes) of the Float32Array from the start of its ArrayBuffer. Fixed at construction time and thus read only.
finallength:Int
Returns the number of elements hold in the Float32Array. Fixed at construction time and thus read only.
