19.456 thousand or 19,456 thousand should therefore be written in English in either of the following ways:
所以，19.456千，或者19,456千应该按照下面这样的方式写才对：
19,456,000 or 19.456 million (read as “nineteen million, four hundred and fifty-six thousand” or “nineteen point four-five-six million”)
19,456,000 或者19.456 million(读作，一千九百四十五万六千)。
