i remember a problem i had once with long shader id. the Id was to long, pd converted it to exponentian notation (1234e+7), so some precision was lost.
Until the ID gets over 16777216, it is ok
I just did a quick test in C++, seems my shader ID's are indeed too big for 32bit float.
int|float: 16777216 Shader ID: 536870913 Shader ID: 2147483649
Possible solutions:
1. use symbols instead of floats 2. use small floats with an internal map from id -> real id 3. split shader ids into as many floats as necessary
I prefer solution 2, as it doesn't change the externally visible interface to the Pd user.
