@@ -4,7 +4,7 @@ In modern JavaScript, there are two types of numbers:
 
 1. Regular numbers in JavaScript are stored in 64-bit format [IEEE-754](https://en.wikipedia.org/wiki/IEEE_754-2008_revision), also known as "double precision floating point numbers". These are numbers that we're using most of the time, and we'll talk about them in this chapter.
 
-2. BigInt numbers, to represent integers of arbitrary length. They are sometimes needed, because a regular number can't safely exceed <code>2<sup>53</sup></code> or be less than <code>-2<sup>53</sup></code>. As bigints are used in few special areas, we devote them a special chapter <info:bigint>.

 So here we'll talk about regular numbers. Let's expand our knowledge of them.
