Tip - Get a calculator that can use HEX, BIN etc!

Octal numbers are used in the chmod command in Un*x. In former times there were machines with 6-bit bytes (as the CDC's), where 2-digit octal numbers "naturally" fit into.

And, to get back to:

[...]decimal equivalence of $7CBA?[...]

I just could ask, what is the hexadecimal equivalence of 1048576? $100000, of course! One should use that number system, where the numbers are expressed in the easiest way. The choice between Hex and Binary is then only a matter of convenience, with Hex grouping 4 (itself a power of 2!) binary digits into one.

I meant some more VIC programming related than file permissions in Unix.

What is the easiest representations of 57005, 48879 and 3735928559 by the way?

First of all: 3735928559=57005*65536+48879

And they are useful values to indicate uninitialised memory, when read in Hex.

By the way, 4711 in decimal equals 11147 in octal. Spooky!

Also,

25DEC = 31OCT

Btw, Hesmon can convert between HEX and DEC and also add and subtract HEX values...

Besides HEX, BIN, DEC and OCT, my calculator can also use PEN (base 5). Have you ever heard of a use for that?

(base 5). Have you ever heard of a use for that?

yes, it is used by accountants who also surf for porn.

Or rather accountants who are used to count on their fingers. Decimal works too, but in a pental (?) number system, you easily get the number of hands (and number of number of hands) required.

I read somewhere that the vikings tended to count in pentads.
