I don't program for retro consoles so this might be a naive suggestion, but could you just approximate it with its 5th degree taylor expansion?
if x is between 0 to pi/2 use tan x = x + 1/3 x3 + 2/15 x5
if x is between pi/2 to pi use tan x = x-pi + 1/3 (x-pi)3 + 2/15 (x-pi)5
(= is approximately here)
any error should only be noticeable very close to pi/2
I went to preorder at this link, but everything I try to add to my cart says
"The products marked with *** , are not available in the requested quantity.
Please decrease quantity for marked products. Thank you"
Any suggestions?
The ps4 could be considered both a console and multimedia machine. The CD-I could be consider both as well. Seems like the discussion is over semantics and not the OP friendly post about a machine that he has a fondness for.
