How do you detect Credit card type based on number?
...at you make the field wide enough to display 32 characters and allow up to 64; that gives plenty of headroom for expansion.
Here's an image that gives a little more insight:

}
Class = 12 + 8 * 4 = 48 bytes
Entry = 32 + 16 + 16 = 64 bytes
Array = 20 + 1000 * 64 = 64024 bytes
Total = 64,136 bytes

What is the difference between Int and Integer?
...ay
recognise the "bignum" type here.
"Int" is the more common 32 or 64 bit
integer. Implementations vary,
although it is guaranteed to be at
least 30 bits.

Generate a Hash from string in Javascript
...ained here, we can extend the hash bit size using this trick:
function hash64(str) {
var h1 = hash32(str); // returns 32 bit (as 8 byte hex string)
return h1 + hash32(h1 + str); // 64 bit (as 16 byte hex string)
}
Use it with care and don't expect too much though.
