A good book would be a book reference for Hexadecimal and PHP, not a math book.

Is this question about PHP programming or just about the mathematics? The mathematics is: "A8" in hexadecimal is the same as 10(16)+ 8= 168 in decimal. Incrementing that, 168+ 1= 169= 10(16)+ 9= "A9" in hexadecimal. Incrementing again,169+ 1= 170= 10(16)+ 10= "AA" in hexadecimal. Incrementing again, 170+ 1= 171= 10(16)+ 11= "AB" in hexadecimal. Incrementing again, 171+ 1= 172= 10(16)+ 12= "AC" in hexadecimal. Incrementing again, 172+ 1= 173= 10(16)+ 13= "AD" in hexadecimal. We can keep on incrementing in exactly that way to 175= 10(16)+ 15= "AF" but after that 175+ 1= 176= 11(16)+ 0= "B0" in hexadecimal. Last edited by skipjack; October 12th, 2017 at 08:21 AM.
