Let (QString|QLocale)::toFloat ignore trailing non-digits

    Description

      The C standard library function atof() works like QString::toFloat for char arrays.

      In contrast to QString::toFloat(), atof() ignores e.g. a trailing unit after the float representation:

      "The rest of the string after the last valid character is ignored and has no effect on the behavior of this function." http://www.cplusplus.com/reference/cstdlib/atof/

      It would be nice, to be able to use QString("1.2345 V").toFloat() also. Currently it returns 0.
