Fix GCC -Wfloat-conversion warnings (available since GCC 4.9)

This warning used to be part of -Wconversion, but that generates too
more noise than we're willing to fix now (like conversion from qint64 to
int). The float conversion does trigger for conversion from double to
float, as shown in all the QVectorND uses of float, but more
importantly, it triggers on passing floats to ints.
