Re: [PD] split number into digits
Hi list, To elaborate on Claude's answer, here is how I would do it in vanilla : #N canvas 355 282 450 300 12; #X obj 214 124 % 10; #X obj 96 126 / 10; #X obj 182 91 t f f; #X floatatom 182 32 5 0 0 0 - - -; #X obj 96 148 i; #X obj 96 172 sel 0; #X obj 214 147 list append; #X obj 214 170 t a a; #X obj 182 54 t f b; #X obj 96 214 list store; #X obj 96 239 print; #X connect 0 0 6 0; #X connect 1 0 4 0; #X connect 2 0 1 0; #X connect 2 1 0 0; #X connect 3 0 8 0; #X connect 4 0 5 0; #X connect 5 0 9 0; #X connect 5 1 2 0; #X connect 6 0 7 0; #X connect 7 0 9 1; #X connect 7 1 6 1; #X connect 8 0 2 0; #X connect 8 1 6 1; #X connect 9 0 10 0; The inconvenient is that your number cannot start with extra zeros, but I guess this is not an issue here. Also, I have no idea how to perform this in other bases ... but it works just fine in base 10 for positive numbers.

Re: [PD] split number into digits
You can do this: - transform "float 512" into "symbol 512" using [makefilename %d] - then transform "symbol 512" into "list 53 49 50" with [list fromsymbol]. - finally subtract 48 (which is the ascii for "0") from every item, you get "5 1 2" Le dim. 17 janv. 2021 à 18:23, Jeppi Jeppi a écrit : > Hi there, > which would be your most elegant way to split a number into a list of > digits? that is, I have the number 512 and I want the list 5 1 2 > ___ > Pd-list@lists.iem.at mailing list > UNSUBSCRIBE and account-management -> > https://lists.puredata.info/listinfo/pd-list > ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list
