Some bank cards run on 32 bit systems.
so if you try and transfer $21,474,836.48 to someone,
you will notice that you don't have $21 million

I don't need to check my account to know I don't have $21 million. :lol:

Never even new your name was on an international money laundering account?
You did have $21 million...I withdrew it yesterday (in two transactions)

The punchline is that 2147482648 is one over the limit of 32 bit system, so you'd expect some sort of bug to happen. But instead of explaining a bug, I just told you you didn't have 2147483648 cents.

Just because some banking system is running 32-bit software wouldn't automatically mean that numbers can only be represented in 32 bits by that software.

IOW there is no 32-bit limit imposed on transactions (and BTW, the maximum 32-bit unsigned integer is 4,294,967,296 - or using signed integers, -2,147,483,648 to 2,147,483,647).

Check out floating point binary representation - for example: https://en.wikipedia.org/wiki/Floating-point_arithmetic

Wikipedia wrote:
On a typical computer system, a double-precision (64-bit) binary floating-point number has a coefficient of 53 bits (including 1 implied bit), an exponent of 11 bits, and 1 sign bit. Since 210 = 1024, the complete range of the positive normal floating-point numbers in this format is from 2−1022 ≈ 2 × 10−308 to approximately 21024 ≈ 2 × 10308


:nerdy: obv.
