I have tried using the modulo operator for small floats and it works perfectly fine.
5 % 2 returns
But for other large floats that are read as exponential in python it just returns
0 every time even if the number is odd.
295147905179352825855 % 2 returns
0 even though that number is clearly odd.
Is there anything I can do to check large floats without python reading it as exponential?
What you said is not true.
295147905179352825855 % 2 should work because Python does arbitrary precision math on integers. There’s no floating-point values in your question
OTOH if you use a float like
295147905179352825855.0 then it obviously won’t work because Python uses IEEE-754 binary64 format which has only 53 bits of precision and can’t store values such as
295147905179352825855.0. The closest value is
295147905179352825856.0 which is clearly an even number
>>> 295147905179352825855 % 2 1 >>> 295147905179352825855.0 % 2 0.0 >>> format(295147905179352825855.0, '.20f') '295147905179352825856.00000000000000000000' >>> 295147905179352825856.0 == 295147905179352825855.0 True
