If you want to print the numbers nicely to the console add [makefilename %f] :
[t b f] | [makefilename %f] | [print count]

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
