Seth Price corrected me (thanks Seth!). I actually only loose one bit
for the sign.
echo (int)pow(2, 31);
> 1073741824
echo (int)pow(2, 32);
> -2147483648
That's certainly a relief.
I don't know if there are other reasons to have unsigned integers. I
certainly don't mind having it. However it is probably a small issue
since PHP automatically cast large numbers to float anyway.
Thank you all,
Ezra
