+description: Return -1 if fromIndex >= ArrayLength - converted values
+info: |
+  22.2.3.13 %TypedArray%.prototype.indexOf (searchElement [ , fromIndex ] )
+
+  %TypedArray%.prototype.indexOf is a distinct function that implements the same
+  algorithm as Array.prototype.indexOf as defined in 22.1.3.12 except that the
+  this object's [[ArrayLength]] internal slot is accessed in place of performing
+  a [[Get]] of "length".
+
+  22.1.3.12 Array.prototype.indexOf ( searchElement [ , fromIndex ] )
+
+  ...
+  4. Let n be ? ToInteger(fromIndex). (If fromIndex is undefined, this step
+  produces the value 0.)
