I think these questions might have been asked before, but why are lots of the celtic commands missing on the CSE? More precisely, commands that have nothing to do with displaying stuff on the screen, like storing a number to a string, storing quotation marks and the "store" arrow to a string and executing a string of hex characters as asm opcodes? Also, whats up with greek letters and most (if not all) tokens when trying displaying them with xlibc? why do they show up all jiggly and wiggly? Some other random question, was there ever a command to convert binary to decimal or vice-versa? I know there was one for hex...

These were Celtic III commands; I ported the smaller, simpler Celtic 2 to the TI-84 Plus C Silver Edition. It focuses entirely on file manipulation functions. xLIBC displays characters rather than tokens, so it renders the one-byte and two-byte tokens that aren't characters as random (missing) sprites. Combine BinToHex with HexToDec.

for that last question, if the numbers are in a list, say of five elements, would it be faster to simply always multiply it by a list containing the first five powers of two rather than using those two hybrid commands?
