round(), int() returns incorrect value

[volzhs]

print(round(123456.0), ",", round(123456789.0), ",", round(1234567890.0))
print(int(123456.0), ",", int(123456789.0), ",", int(1234567890.0))

both cases prints 123456,123456792,1234567936

sounds like precision issue. My guess is underneath implementation uses single-precision.

Yes like @choikwa says, I guess it's a matter of using single precision for floats, and thus numbers with 10 significant digits like your second one show precision issues.

See #288 for a request to add double precision support.

I'll close the issue as I believe it's not a bug but just a consequence of #288 not being solvd yet, though feel free to tell me if you think this is not the appropriate resolution.
