Re: [PD] problem with correct numbers in pd double precision / problem with div and mod
the onyl thing i don´t like about the [makefilename %.0f] method is, that for big amount of data, it may clutter the symboltable. so i started investigating alternativ ways of storing big numbers in chunks, using the [div] and [mod] objects. but they only go until 2147483647 after which they overflow and produce wrong results. anything special about this number? seems [div] and [mod] are not fully double yet. demo patch attached hans big-numbers4_div-mod.pd Description: Binary data > Am 23.09.2020 um 10:34 schrieb hans w. koch : > > lucas thanks for alerting me to >> Attached patch edited to show that it is "no go" using txt files. > its indeed a major headache :-( > conclusion: the only reliable way using [text] with big numbers is with > from/tosymbol. > > i totally agree, it would be good to be able to write/read 64bit-arrays. > what i like about [text] is multi column data - though it gets really slow > with bigger files. > > hans > >> Am 21.09.2020 um 10:46 schrieb Lucas Cordiviola : >> >> On 9/20/2020 2:38 PM, hans w. koch wrote: >>> but would it warrant opening an issue on github? >> >> There should be some way to write/read 64bit arrays in Pd-double.
