And sorry for the spam (this should have been mentioned in the last
email), as far as I can tell, there is no-way to say "I want a either a
signed or unsigned integer with an N bits", I've come across this
recently whilst trying to implement Murmur3 (128-bit) in PHP, I can
of-course binary AND into
$x & 0b11...) and it will yield result of 9,223,372,036,854,775,807
((2^63)- 1 (PHP_INT_MAX)) but adding an additional 1 (radix 10) will
yield a double(9.2233720368548E+18) and it's at that point it becomes
incredibly difficult to work with to work with natural numbers.
(Unrelated to Sara's RFC, just a thought I'd mention incase someone is
I personally think this RFC is fine despite the existing libraries that
do similar (BCMath and GMP), it's more of an interface to the lower
layer (and OpenSSL specific) rather than an implementation. We're just
keeping up with existing implementations.
Sara, I'm happy to implement additional tests and look at fast ZPP for
methods tomorrow if you're too busy and think this is going somewhere...
