  Set values and return undefined

  24.2.4.13 DataView.prototype.setFloat32 ( byteOffset, value [ , littleEndian ] )

  1. Let v be the this value.
  2. If littleEndian is not present, let littleEndian be false.
  3. Return ? SetViewValue(v, byteOffset, littleEndian, "Float32", value).

  24.2.1.2 SetViewValue ( view, requestIndex, isLittleEndian, type, value )

  ...
  15. Let bufferIndex be getIndex + viewOffset.
  16. Return SetValueInBuffer(buffer, bufferIndex, type, numberValue, isLittleEndian).

  24.1.1.6 SetValueInBuffer ( arrayBuffer, byteIndex, type, value [ , isLittleEndian ] )

  ...
  8. If type is "Float32", then
    a. Set rawBytes to a List containing the 4 bytes that are the result of
    converting value to IEEE 754-2008 binary32 format using “Round to nearest,
    ties to even” rounding mode. If isLittleEndian is false, the bytes are
    arranged in big endian order. Otherwise, the bytes are arranged in little
    endian order. If value is NaN, rawValue may be set to any implementation
    chosen IEEE 754-2008 binary32 format Not-a-Number encoding. An
    implementation must always choose the same encoding for each implementation
    distinguishable NaN value.
  ...
  11. Store the individual bytes of rawBytes into block, in order, starting at
  block[byteIndex].
  12. Return NormalCompletion(undefined).
