I was considering downgrading this to 'normal'. Then I found Bug 8, and it's a biggie: >>> 10.900000000000000012345678912345678912345 10.0 Now I'm thinking it should be upgraded to release blocker instead. The cause is in the _Py_strtod block that starts: 'if (nd > STRTOD_DIGLIM) {'... It truncates the input to 18 digits, and then deletes trailing zeros. But the code that deletes the zeros is buggy, and passes over the digit '9' just before the point.
