 A factory that produces BN.js constructors for a given width
 
 **Parameters**
 
--   `maxWidth` **Integer** the max length in bits that the bn.js instance can handle
--   `minWidth` **Integer** the min length in bits that the bn.js instance can handle
+- `maxWidth` **Integer** the max length in bits that the bn.js instance can handle
+- `minWidth` **Integer** the min length in bits that the bn.js instance can handle
 
 Returns **bn.js** returns a bn.js constuctor that that is constained to `maxWidth` and `minWidth`
 
 ## builtin length

 the factory has the following builtins
+
 - `FixedBN.U64`
 - `FixedBN.U128`
 - `FixedBN.U160`
 - `FixedBN.U256`
 
 ## bn.js instance
