I can confirm however I wonder if it could be ... floating point accuracy.
What rounding is performed when float is converted to integer ? Truncation
towards zero ? Could it be that -1 is internally something like -0.99999999999
and after truncation it is valid value 0 ? If yes then possible fix is to
check sign of the float before conversion to int.
