Type conversions on ToNumber(src property value)

22.2.3.23.1 %TypedArray%.prototype.set (array [ , offset ] )
1. Assert: array is any ECMAScript language value other than an Object with a
[[TypedArrayName]] internal slot. If it is such an Object, the definition in
22.2.3.23.2 applies.
...
21. Repeat, while targetByteIndex < limit
a. Let Pk be ! ToString(k).
b. Let kNumber be ? ToNumber(? Get(src, Pk)).
c. If IsDetachedBuffer(targetBuffer) is true, throw a TypeError exception.
d. Perform SetValueInBuffer(targetBuffer, targetByteIndex, targetType,
kNumber).
