thanks lucas, transitioning numbers over to symbolland could solve my problem, interesting to know.
i need to store some of the big numbers in a textfile and there i get the same problems with representation. if i recall them later, they´ve lost their precision. so i can make the transition back from symboldland with a bit of fudi objects voodoo and be good :-) what i use is this: [makefilename %f] | [list trim symbol] | [fudiformat -u] | [fudiparse] and have my number back from symbol. best hans > Am 19.09.2020 um 05:32 schrieb Lucas Cordiviola <lucard...@hotmail.com>: > > If you want to print the numbers nicely to the console add [makefilename %f] : > > [t b f] > | > [makefilename %f] > | > [print count] > > > Be aware of https://github.com/pure-data/pure-data/issues/812 > > :) > > Mensaje telepatico asistido por maquinas. > > On 9/18/2020 6:12 PM, hans w. koch wrote: >> hello, >> >> its probably due to my lack of understanding the correct number >> representations, but here it goes anyway: >> >> i compiled pd 51-2 double precision for mac 10.14.6 >> with this version i was hoping to do some maths on big numbers. >> but already an increment of 1 on some moderatly big number gives me problems >> of representation. >> >> i made a simple version of the problem as a patch. >> to verify you have a working version of pd double, it contains a simple test. >> and then an iterative addition +1 starting from 999999. >> i get this: >> count: 999999 >> count: 1e+06 >> count: 1e+06 >> count: 1e+06 >> count: 1e+06 >> count: 1e+06 >> count: 1.00000e+06 >> count: 1.00001e+06 >> count: 1.00001e+06 >> count: 1.00001e+06 >> >> the algorith terminates succesfully by a [select] after 10 iterations, but >> the results don´t show what i expect. >> this to me indicates, that the internal numbers are correct, but they don´t >> “surface” as such. >> >> i would be grateful for any pointers and possible workarounds, as the >> numbers i hope to be dealing with are potentially orders of magnitude higher. >> >> thanks hans >> >> >> _______________________________________________ >> Pd-list@lists.iem.at mailing list >> UNSUBSCRIBE and account-management -> >> https://lists.puredata.info/listinfo/pd-list >> <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
