@ -20,10 +20,10 @@ When this code is run , the Applesoft parser will perform the following:
* then ``1``
* then ``5``
* then ``2``
5. Collating these, results in ``4 9 1 5 2`` as 5 ASCII characters. These represent, for us, humans, a decimal number but not yet for Applesoft.
6. These 5 characters will then be converted to a real number (using a format known as binary floating-point format)
7. Then, the real number is converted to an integer value (because ``PEEK`` expects a 2-bytes integer)
8. Once this has been done, the value in the appropriate location is read, converted from byte to a binary floating-point value and attributed to variable K

The bottleneck here are the steps 4-6. Building a integer representing a memory location from characters is long.
