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

it's a limitation of 32 bit float
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.
