20.1.3 Properties of the Number Prototype Object
The Number prototype object is the intrinsic object %NumberPrototype%. The
Number prototype object is an ordinary object. The Number prototype is itself
a Number object; it has a [[NumberData]] internal slot with the value +0.
[...]
The abstract operation thisNumberValue(value) performs the following steps:
1. If Type(value) is Number, return value.
2. If Type(value) is Object and value has a [[NumberData]] internal slot, then
a. Assert: value's [[NumberData]] internal slot is a Number value.
b. Return the value of value's [[NumberData]] internal slot.
3. Throw a TypeError exception.
Number.prototype.toPrecision ( precision )
1. Let x be ? thisNumberValue(this value).
2. If precision is undefined, return ! ToString(x).
