this mean that it's compiled for 64 bit CPU, not that float are store on 64 bits you can have 8 bit int, 32 bit float and 64 bit float (and more) on a 32 bit CPU. and also on a 64 bit CPU. even 8 bit cpu can deal with 32/64 bit float... cheers c
what now? :) 2015-01-28 14:41 GMT-02:00 Cyrille Henry <[email protected] <mailto:[email protected]>>: Le 28/01/2015 17:20, Alexandre Torres Porres a écrit : howdy, check the attached patch. 1e+06 + 1 is not equal to 1e+06 but 1e+09 + 1 is equal to 1e+09 meaning it didn't add 1 to 1e+09! Meaning there's a limit where it stops adding 1 to something. how's that and why? it's a limitation of 32 bit float. since 1 bit is used for the sign, 8 for the exponent, 23 bit are left for the significant. this mean that you can't have more precision in the significant than 2^24 -1 (a bit less than 1.7*10^7) cheers c cheers _________________________________________________ [email protected] <mailto:[email protected]> mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/__listinfo/pd-list <http://lists.puredata.info/listinfo/pd-list> _________________________________________________ [email protected] <mailto:[email protected]> mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/__listinfo/pd-list <http://lists.puredata.info/listinfo/pd-list> _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
