The idea is that the default would be 6464, but restricted systems Just so I understand, what was the rationale for choosing 64 over 32 as the integer size? I was a little surprised by that given that integers would seem most useful on more restricted platforms where 64bit integer is still (moderately) expensive (and also even that many "64bit" OSes are compiled with 32bit integers, such as OS X). I suppose I was expecting something more like a 32bit integer that would seamlessly overflow into a regular double if necessary. Tim
