An other advantage IMHO is that 64-bit integers can represent any integer
that can - in float format - be distinguished from it's neighbour.
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.
