  2. Let i be ? ValidateAtomicAccess(typedArray, index).

  ValidateAtomicAccess( typedArray, requestIndex )

  2. Let accessIndex be ? ToIndex(requestIndex).

  ToIndex ( value )

  2. Else,
    a. Let integerIndex be ? ToInteger(value).

  ToInteger(value)

  1. Let number be ? ToNumber(argument).

    Symbol --> Throw a TypeError exception.
