Re: [Zend Engine 2] Bumping PHP to support 8byte integers

Recall that C-double == PHP-float have at least 64-bits, so a mantissa of <64bits. So any number n for which n and n+1 are distingwishable in 64-bit floating point numbers, must fall in the range of 64-bit integers. > For implementation, I think that we should introduce p_int and p_float > typedefs for php-integer and php-float anyway, and changing THAT isn't a > problem. > > About preformance/memory, I think that's not an issue.
