Key for modular arithmetic - Alberto Candel - 03-31-2018 03:32 PM
Good morning, In CAS, modular arithmetic can be performed with the "%%" symbol. As far as I know, typing that requires about 9 keystrokes (the % symbol is in the Chars table). Is there a shortcut for "mod" in CAS? I tried creating a userkey program, but cannot do much better because one must use the MOD operator, it doesn't work with the %%. Any help would be welcome. Thanks. RE: Key for modular arithmetic - Carlos295pz - 03-31-2018 03:41 PM
It should work with MOD, if it requires a function own of CAS can use irem(). RE: Key for modular arithmetic - Alberto Candel - 03-31-2018 03:54 PM

What I was wondering was if there is a single keystroke that would perform say 2^36 %% 73. Typing the two %% takes a while, and looking up MOD does too.

Hello, I know it isn't much consolation, but you should be able to do SHIFT-CHARS, TAP % Double tap %, then press ENTER or OK and put both in at once. RE: Key for modular arithmetic - Alberto Candel - 03-31-2018 09:07 PM

Perhaps there is a way to leave the USER keyboard on for more that just one keystroke, is there? RE: Key for modular arithmetic - Carlos295pz - 04-01-2018 01:18 AM
