Well, thanks everyone.

And now for some related issues.

Pd can only represent up to 6 significant digits, so they say. For example, in a message, you can have a number with up to 5 decimal places, like: -5.29314e+12 

but it does have a better internal resolution, if you compare 4 / 3 to 1.33333 you'll see 4 / 3 is higher ( try [expr 4./3 > 1.33333] and check).

So, what's this internal resolution? And why can't you have the same resolution in a message?

thanks

I thought so, but same happens when I use the new Pd Vanilla 64 bits...

this mean that it's compiled for 64 bit CPU, not that float are store on 64 bits

Also last time I checked, Pd saves floats by first printing them to 6 digit precision, so they have even less range than a 'float' type.

You could use an object made with pdlua to manipulate large floating-point numbers, as there is no(?) limit to the size of a float in lua.
