Re^2: Perl can't make some easy arithmetics :(

Could it be you are on a 64 bit system?

Perl automatically switches to floating point representation˛ if the integer range is exceededš.

Oh yes you did an update showing the bits :)

š) 2**31 < 900000000000000009 < 2**63

˛) IIRC does Perl's FP mantissa have 56 bits so 7.2e+16 ~~ 2**56 < 900000000000000009 ~~ 9e+17

It's 52 bits, not 56. Double-precision floating-point format #pedantry	[reply]

For a total precision of 53 bits because of the implied leading `1`.	[reply] [d/l]
